Description

Technical Field

[0001] The utility model relates to the technical field of ship engineering, in particular to a deep-water flow field flow-making system. Background Art

[0002] In deepwater environments, varying flow fields and pressures significantly impact the performance of deepwater equipment. Therefore, performance testing of deepwater equipment prior to launch is essential. Deepwater flow systems, the primary system for deepwater testing, simulate deepwater flow environments to facilitate deepwater testing and research.

[0003] There are two main types of deep-water flow systems: in-pool and out-pool. In the in-pool circulation system, a water pump pushes water from one end of the pool to the other to form a flow field. In the out-pool circulation system, a water pump is installed outside the pool, pumping water from one side of the pool and letting water in from the other side to form a flow field inside the pool.

[0004] At present, in the research of deep-water flow generation systems, the study on how to form a stable flow field is a relatively core topic. Based on this, the present application proposes a deep-water flow field generation system that can form a stable flow field. Utility Model Content

[0005] Based on the above description, the utility model provides a deep-water flow field flow generation system capable of forming a stable flow field.

[0006] The technical solution of the utility model to solve the above technical problems is as follows:

[0007] This application provides a deep-water flow field flow generation system, the technical solutions adopted are as follows:

[0008] A deep-water flow field flow generation system, comprising:

[0009] A pressure vessel having a fluid inlet at one end and a fluid outlet at the other end;

[0010] a circulation system comprising a piping system and a circulation pump provided outside the autoclave, wherein the piping system connects a fluid inlet and a fluid outlet, and the circulation pump is connected to the piping system to provide power for fluid circulation;

[0011] The fairing device is arranged in the pressure autoclave and located at the fluid inlet, including a fairing and a fairing guide core. One end of the fairing is connected to the fluid inlet, and the diameter of the fairing gradually increases in the direction away from the fluid inlet. The fairing guide core is arranged in the fairing and connected to the fairing. The fairing guide core is in the shape of a teardrop with a diameter gradually decreasing from the middle to the two ends in the axial direction of the fairing.

[0012] Preferably, both end faces of the fairing core in the axial direction of the fairing are spherical.

[0013] Preferably, the teardrop-shaped tip of the rectifying guide core faces away from the fluid inlet.

[0014] Preferably, the fairing guide core is connected to the fairing through a plurality of connecting plates, the plurality of connecting plates are evenly spaced in the circumferential direction of the fairing axis, and the connecting plate surfaces are parallel to the fairing axis.

[0015] Preferably, the two side surfaces of the connecting plate in the axial direction of the fairing are arc surfaces.

[0016] Preferably, the pipeline system is connected to a flow measuring device for measuring fluid flow.

[0017] Compared with the prior art, the technical solution of this application has at least the following beneficial technical effects:

[0018] 1. The fluid generation system of the present application comprises a pressure vessel and a circulation system. Fluid is discharged from the pressure vessel through the fluid outlet, passes through a piping system, and then is input into the pressure vessel through the fluid inlet, forming a flow field within the pressure vessel. A circulation pump provides power for the liquid circulation. By installing a rectifier at the fluid inlet within the pressure vessel, the fluid enters the pressure vessel and enters the fairing. Within the fairing, the fluid passes through a rectifier core. The structural design of the rectifier core minimizes the pressure drop of the fluid after exiting the rectifier, forming a stable flow field between the fairing and the fluid outlet. The fluid velocity distribution is uniform across the cross-section of the flow field. In other words, the rectifier enables a stable and uniform flow field to be formed within the pressure vessel.

[0029] Reference Figure 1-3As shown, an embodiment of the present application provides a deep-water flow field flow generation system, comprising a pressure vessel 1, a circulation system, and a rectifying device. The pressure vessel 1 is provided with a fluid inlet 11 at one end and a fluid outlet 12 at the other end. The circulation system comprises a piping system 2 and a circulation pump 3 provided outside the pressure vessel 1. The piping system 2 connects the fluid inlet 11 and the fluid outlet 12. The circulation pump 3 is connected to the piping system 2 to provide power for fluid circulation. The rectifying device is provided within the pressure vessel 1 and is located at the fluid inlet 11. It comprises a fairing 4 and a rectifying core 5. One end of the fairing 4 is connected to the fluid inlet 11. The diameter of the fairing 4 gradually increases as it moves away from the fluid inlet 11. The rectifying core 5 is provided within the fairing 4 and is connected to the fairing 4. The rectifying core 5 is in the shape of a water droplet, the diameter of which gradually decreases from the middle to both ends in the axial direction of the fairing 4.

[0030] Reference Figure 1 As shown, the fluid exits the autoclave 1 from the fluid outlet 12, passes through the piping system 2, and is then input into the autoclave 1 from the fluid inlet 11, forming a flow field within the autoclave 1. The circulating pump 3 provides power for the liquid circulation. By installing a rectifying device at the fluid inlet 11 within the autoclave 1, the fluid enters the fairing 4 after entering the autoclave 1. Within the fairing 4, the fluid passes through the rectifying core 5. The structural design of the rectifying core 5 minimizes the pressure drop of the fluid after exiting the rectifying device, forming a stable flow field between the fairing 4 and the fluid outlet 12. The fluid velocity distribution is uniform across the cross-section of the flow field. In other words, the rectifying device enables a stable and uniform flow field to be formed within the autoclave 1.

[0031] Reference Figure 1 As shown, the autoclave 1 specifically includes a main section 13 and an outlet section 14. The main section 13 is cylindrical with a horizontal axis. Both ends of the main section 13 are closed and spherical. The outlet section 14 is located at one end of the main section 13 and is coaxial with and connected to the main section 13. The fluid outlet 12 is located on the sidewall of the outlet section 14, and the fluid inlet 11 is located at the end of the main section 13 away from the outlet section 14. Pipe interfaces are provided on both the fluid inlet 11 and the fluid outlet 12 of the autoclave 1 for connection to the piping system 2.

[0032] Reference Figure 1 As shown, the piping system 2 is constructed by selecting appropriate pipes and expansion joints based on design requirements to connect the fluid inlet 11 and fluid outlet 12 of the autoclave 1. A circulation pump 3 is provided on the piping system 2 to provide power for fluid circulation. Furthermore, to monitor the fluid flow rate within the piping system 2, a flow measuring device 6 is connected to the piping system 2 to measure the fluid flow rate within the piping system 2 for monitoring and control. Specifically, a flow meter can be used as the flow measuring device 6.

[0033] Reference Figure 1-2As shown, the flow straightening device is designed to create a stable and uniform flow field for the fluid within the autoclave 1. The smaller end of the fairing 4 is connected to the fluid inlet 11, allowing the fluid entering the autoclave 1 to be fed into the fairing 4. Specifically, the fairing 4 and autoclave 1 are coaxially arranged, and the outlet diameter (i.e., the maximum diameter) of the fairing 4 is designed based on the desired flow field diameter. Within the fairing 4, the fluid, through the fairing 4 and the fairing core 5, forms a stable and uniform flow field in the area behind the fairing 4 in the direction of fluid flow. The pressure drop of the fluid after passing through the fairing 4 is minimal, and the resulting flow field pressure meets the design requirements.

[0034] Reference Figure 1-2 As shown, specifically, the rectifying guide core 5 is configured so that the end faces at both ends in the axial direction of the fairing 4 are spherical. At the same time, the teardrop-shaped tip of the rectifying guide core 5 faces away from the fluid inlet 11 to reduce the resistance of the rectifying guide core 5 to the fluid, and enable the fluid to form a stable and uniform flow field after passing through the rectifying guide core 5.

[0035] Reference Figure 2-3 As shown, the fairing core 5 is connected to the fairing 4 via a plurality of connecting plates 7. The plurality of connecting plates 7 are evenly spaced and distributed circumferentially along the axis of the fairing 4. The surface of the connecting plates 7 is parallel to the axis of the fairing 4. Specifically, one end of the connecting plate 7 is fixed to the middle of the fairing core 5, and the other end is fixed to the inner wall of the fairing 4. The length direction of the connecting plate 7 is perpendicular to the axis of the fairing 4. In order to further reduce the resistance of the connecting plate 7 to the fluid, the two side surfaces of the connecting plate 7 in the axial direction of the fairing 4 are set as curved surfaces. This is so as to reduce the resistance of the connecting plate 7 to the fluid while achieving a stable connection between the fairing core 5 and the fairing 4 through the connecting plate 7.

[0036] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
