Description

Detailed Description of the Invention

[0001] 〔Technical Field of the Invention〕 The present invention relates to the field of equipment, devices and / or procedures for hydrodynamic testing or trials. In particular, the present invention provides a system and method for generating tsunamis with reversible flow under laboratory conditions.

[0002] 〔Background of the Invention〕 Tsunamis are complex phenomena, and it has been difficult to reproduce their behavior in the laboratory. The systems currently existing in the prior art simulate only waves in one direction, either without backflow or generating short-period waves that do not correspond to actual-scale tsunamis.

[0003] For example, JPH07120352A discloses a water tank for simulating annular flow. The water tank includes a pair of counter-rotating impellers arranged in an annular passage of the water tank for circulating upward and downward in the water tank, respectively.

[0004] On the other hand, CN101561345A provides a two-way experimental water tank for hydraulics and sediment mechanics. The two-way experimental water tank includes a water tank with symmetric water outlets provided at two ends of the water tank, a plurality of transition sections communicating with the plurality of water outlets, a main pipe arranged between the plurality of transition sections, a two-way axial-flow water pump, an electric control valve, and a two-way electromagnetic flowmeter alternately arranged in the main pipe, and a motor for driving the water pump controlled by a variable-frequency actuator.

[0005] However, in terms of both the time scale of actual phenomena and the conditions of flow depth and speed, the prior art has deficiencies in providing a system that enables reproduction of both the flooding and backflow stages. Therefore, there is a need for a system and method to overcome the deficiencies of the prior art.

[0006] 〔Summary of the Invention〕 The present invention provides a system for generating tsunamis with a reversible flow under laboratory conditions.

[0008] 〔Brief Description of the Drawings〕 FIG. 1 is a schematic side view of a first embodiment of a system which is the subject of the present invention.

[0009] 〔Detailed Description of the Invention〕 Hereinafter, the present invention will be described in detail with reference to the accompanying drawings of the present application.

[0010] In a first aspect of the present invention, a system for generating a tsunami with a reversible flow under laboratory conditions is provided. The system includes an elongated simulation channel (1) having a first side region, a second side region located opposite the first side region, and a measurement region located between the first side region and the second side region, a first fluid outlet, a first bottom gate (9) configured to open and close the first fluid outlet, and a first pop-up gate (10) disposed within the first side region, a second fluid outlet, a second bottom gate (11) configured to open and close the second fluid outlet, and a second pop-up gate (12) disposed within the second side region, at least one fluid drive pump (2), flow measurement and control means (4, 6, 7), a first fluid inflow pipeline (8) configured to inject fluid into the first side region, a second fluid inflow pipeline (15) configured to inject fluid into the second side region, a control system (17, 18) for at least one of the drive pumps (2), the first bottom gate (9), the second bottom gate (11), the first pop-up gate (10), the second pop-up gate (12), and the flow measurement and control means (4, 6, 7), and substantially includes.

[0011] In the context of the present application, although not limiting the scope of the present application, the expression "at least one" shall be understood as one or more of the recited elements. The number of elements referred to by the expression "at least one" does not limit the scope of the present application. Further, if two or more elements are provided that are referred to by the expression "at least one", these elements do not limit the scope of the present application, but may be identical to each other or not identical to each other.

[0012] In the context of the present invention, without limiting the scope of the present application, the simulation channel (1) is understood to have an elongated shape when its length in one direction (understood as the elongated direction) is much larger than its length in both of the two directions perpendicular to the elongated direction. In this regard, for example, without limiting the scope of the present invention, the length in the elongated direction may be more than 5 times the length in both of the two perpendicular directions, preferably more than 10 times the length in both of the two perpendicular directions, and even more preferably more than 20 times the length in both of the two perpendicular directions.

[0013] Furthermore, without limiting the scope of the present invention, it will be understood that the first side region and the second side region are arranged laterally with respect to the elongated direction of the elongated channel (1). As long as the first side region and the second side region extend along the elongated direction of the elongated channel (1) so that a simulation region located between the first side region and the second side region is obtained, it does not limit the scope of the present invention. Furthermore, the first side region and the second side region, without limiting the scope of the claimed protection, may or may not have the same extent. In a preferred embodiment, without limiting the scope of the present invention, the first side region and the second side region have the same extent.

[0014] The elongated channel (1) forming part of the system which is the subject of the present invention further includes a simulation region located between the first side region and the second side region. The extent of the simulation region along the elongated direction of the elongated channel (1) will, without limiting the scope of the present invention, depend, for example, on the extent of the first side region and the second side region, and the length of the elongated channel (1) along the elongated direction.

[0015] Preferably, although not limiting the scope of the present invention, one or more elements enabling the obtaining of measurement values when simulating a specific phenomenon may be arranged in the simulation region. For example, although not limiting the scope of the present invention, at least one fluid level (height) sensor, at least one longitudinal fluid velocity sensor, at least one lateral fluid velocity sensor, at least one video camera, at least one image capture camera, at least one light source, at least one fluid pressure sensor, at least one fluid temperature sensor, and combinations thereof may be arranged in the said region of the simulation.

[0016] In a preferred embodiment, although not limiting the scope of the present invention, the measurement region may include a change in depth. The change in depth may be a depression that is deeper than the first side region and the second side region, or a protrusion that is shallower than the first side region and the second side region. In this region where the depth changes, it may be possible to install elements for testing and additional elements for measuring hydrodynamic variables that enable the simulation of a specific phenomenon. For example, in a preferred embodiment, although not limiting the scope of the present invention, a scaled - down coastal structure, a scaled - down building, a gently sloping coast with fixed materials, a gently sloping coast with removable granular materials, a scaled - down relaxation forest, a power generation system, a pressure measurement device, or an immersion pump may be arranged in the said depression. In this embodiment, furthermore, although not limiting the scope of the present invention, the system may include a discharge pipeline that fluidly connects the immersion pump to a fluid storage tank.

[0017] The system which is the subject of the present invention includes a first bottom gate (9) configured to selectively control, by opening and closing it, a first fluid outlet from the elongated channel (1), and a first pop-up gate (10) disposed within the first side region of the elongated channel (1). Similarly, the system which is the subject of the present invention includes a second bottom gate (11) configured to selectively control, by opening and closing it, a second fluid outlet from the elongated channel (1), and a second pop-up gate (12) disposed within the second side region of the elongated channel (1).

[0018] In the context of the present invention, although not limiting the scope of the present invention, it will be understood that the bottom gate (either the first bottom gate (9) or the second bottom gate (11)) enables opening and closing of its corresponding fluid outlet (either the first fluid outlet or the second fluid outlet, respectively). For this purpose, the bottom gates (9, 11) can reach at least two positions (referred to as the open position and the closed position, respectively). However, in some preferred embodiments, although not limiting the scope of the present invention, the bottom gates (9, 11) can further reach at least one intermediate position between the open position and the closed position. The means for enabling the bottom gates (9, 11) to move from the open position to the closed position or from the closed position to the open position are not limiting the scope of the present invention. For example, in a preferred embodiment, although not limiting the scope of the present invention, the bottom gates (9, 11) can perform a substantially horizontal (lateral) movement between the open position and the closed position. In another embodiment, although not limiting the scope of the present invention, the bottom gates (9, 11) can perform a pivotal movement between the open position and the closed position. Further, one or more actuators and one or more transmission elements may be provided to enable control of the position of the bottom gates (9, 11). For example, although not limiting the scope of the present invention, a motor, a hydraulic arm, a pneumatic arm, a chain, a rope, a spring, and combinations thereof may be provided to control the position of the bottom gates (9, 11).

[0019] Note that, without limiting the scope of the present invention, it should be understood that the first bottom gate (9) and the second bottom gate (11) may be identical to each other or may not be identical to each other. Further, without limiting the scope of the present invention, the means provided for controlling the positions of the first bottom gate (9) and the second bottom gate (11) may be identical to each other or may not be identical to each other.

[0020] In the context of the present invention, without limiting the scope of the present application, it will be understood that a pop-up gate (either the first pop-up gate (10) or the second pop-up gate (12)) enables control of the water level within the measurement area. For this purpose, the pop-up gate (10, 12) can reach at least two positions (a position referred to as the storage position and a position referred to as the deployment position). Here, the storage position is a position where the pop-up gate (10, 12) does not protrude with respect to the bottom of the corresponding side region, and the deployment position is a position where the pop-up gate (10, 12) protrudes with respect to the bottom of the corresponding side region. However, in some preferred embodiments, without limiting the scope of the present invention, the pop-up gate (10, 12) can further reach a plurality of deployment positions. At each of the plurality of deployment positions, the pop-up gate (10, 12) protrudes at a corresponding height with respect to the bottom of the corresponding side region. The means for enabling the bottom gate (9, 11) to shift from the storage position to the deployment position or from the deployment position to the storage position is not limited to the scope of the present invention. For example, in a preferred embodiment, without limiting the scope of the present invention, the pop-up gate (10, 12) can move substantially vertically (longitudinally) between the storage position and the deployment position. In another embodiment, without limiting the scope of the present invention, the pop-up gate (9, 11) can perform a pivotal movement between the storage position and the deployment position. Further, one or more actuators and one or more transmission elements for enabling control of the position of the pop-up gate (10, 12) may be provided. For example, without limiting the scope of the present invention, a motor, a hydraulic arm, a pneumatic arm, a chain, a rope, a spring, and combinations thereof may be provided for controlling the position of the bottom gate (10, 12).

[0021] Note that, although not limiting the scope of the present invention, it should be understood that the first pop-up gate (10) and the second pop-up gate (12) may be identical to each other or may not be identical to each other. Further, although not limiting the scope of the present invention, the means provided for controlling the positions of the first pop-up gate (10) and the second pop-up gate (12) may be identical to each other or may not be identical to each other.

In a more preferred embodiment, although not limiting the scope of the present invention, at least one of the drive pumps (2) may include a corresponding frequency converter in order to control the flow rate of the fluid driven by at least one of the drive pumps (2).

[0023] The system which is the subject of the present invention further includes flow measurement and control means (4, 6, 7). The flow measurement and control means (4, 6, 7) have the purpose of controlling the flow rate and direction of the fluid circulating through the main fluid pipeline (5) and the first and second side inflow pipelines (8, 15). In this regard, the flow measurement and control means (4, 6, 7) may include valves, flow sensors, diverters, stopcocks, and combinations thereof, but are not limited thereto.

[0025] In another preferred embodiment, without limiting the scope of the present invention, the computer or processor (18) controls at least one fluid drive pump (2) and flow measurement and control means (4, 6, 7) operatively connected to the main fluid pipeline (5), and may be further configured to control whether the flow direction follows the first fluid inflow pipeline (8) or the second fluid inflow pipeline (15). In this case, for example, without limiting the scope of the present invention, the computer or processor (18) controls the positions of the first bottom gate (9), the first pop-up gate (10), the second bottom gate (11), and the second pop-up gate (12), and can control the flow rate of the fluid circulating through the main fluid pipeline (5) and whether the flow follows the first inflow pipeline (8) or the second inflow pipeline (15).

For example, without limiting the scope of the present invention, the system may include a first fluid height sensor disposed in the first side region, a second fluid height sensor (16) disposed in the second side region, and a third fluid height sensor (13) disposed in the measurement region. If provided, without limiting the scope of the present invention, any option known to those skilled in the art may be used as the fluid height sensor. In one embodiment, without limiting the scope of the present invention, if a computer or processor (18) is provided, the computer or processor (18) may be operatively connected to at least one fluid height sensor. In this case, the computer or processor (18) acquires at least one measurement value from at least one fluid height sensor and uses the information to control the positions of the first bottom gate (9), the second bottom gate (11), the first pop-up gate (10), and the second pop-up gate (12), and / or to control the direction and flow rate of the fluid circulating through the main fluid pipeline (5) and through the first fluid inflow pipeline (8) or the second fluid inflow pipeline (15).

[0027] On the one hand, a method in which the first fluid inlet pipe (8) and the second fluid inlet pipe (15) each inject fluid into the first side region and the second side region does not limit the scope of the present invention.

However, without limiting the scope of the present invention, in other preferred embodiments, the elongated channel (1) may include a connection portion (e.g., a threaded connection).

[0033] As described in detail above, it is possible to obtain a system and method that can overcome the deficiencies of the prior art.

[0034] It should be understood that the various options described for the technical features of the system and / or method do not limit the scope of the claimed protection, but can be combined with each other or with other alternatives known to those skilled in the art.

[0035] Examples of the application of the system and method that are the subject of this application are shown below. These examples are provided merely to better understand the present technology and should not be construed as limiting the scope of the claimed protection in any case. Further, although not limiting the scope of protection, the details of the technical features described in the various examples may be combined with each other in any manner, or with the other options described above or other options known to those skilled in the art.

[0036] (Example 1: Implementation form of a tsunami generation system at the laboratory scale) As schematically shown in FIG. 1, a system for generating a tsunami with a reversible flow was constructed. The system has an elongated channel (1) with a length of 20 m. The system has a set of multiple centrifugal pumps (2). Water is sucked up from an underground reservoir (3) by the set of multiple centrifugal pumps (2) and sent into the elongated channel (1) through a pipe (5). Further, a set of multiple electromagnetic flow meters (4) for flow rate control and a set of multiple valves (6, 7) for flow direction control are provided.

[0037] To conduct an experiment in one direction from the left side to the right side of FIG. 1, open the first valve (6), close the second valve (7), and allow the flow to enter the elongated channel (1) from the left side (8). The left bottom gate (9) remains closed, and the left pop-up gate (10) remains in the retracted position. On the other hand, the right bottom gate (11) is fully open, and the right pop-up gate (12) gradually rises to control the height of the flow. The height of the flow is measured by the height sensor (13).

[0038] The excess flow over the pop-up gate (12) drops into the pipe (14), and the flow is directed to the underground reservoir (3).

[0039] Once the one-way experiment is completed, the flow is stopped, the right bottom gate (11) is closed, the first valve (6) is closed, and the second valve (7) is opened. Further, the flow is pumped through the right pipe (15) by the pump (2) so as to be supplied to the elongated channel (1) from the right side. The water level is measured by the right height sensor (16) until the existing water level is reached. Once the existing water volume is reached, the pump is stopped.

[0040] At the same time, the left pop-up gate (10) slowly rises until the desired height is reached, and subsequently, the right pop-up gate (12) slowly descends to the bottom of the channel. Then, the left bottom gate (9) is opened to empty the volume of water located to the left of the left pop-up gate (10). Under this condition, the flow is started in the reverse direction, and the flow through the right pipe (15) is driven by the pump (2). The height is controlled by the left gate (10) descending while being controlled. The excess water drops into the pipe (14) and is directed to the reservoir (3).

[0041] All components of the system are controlled by an electric panel (17) and a computer (18) having software specially developed for this system.
