Embodiment Construction
[0019] The present invention will be further described below in conjunction with the accompanying drawings.
[0020] The object of the present invention is to provide a method and an experimental device for simulating coastal rip current in a towing pool. The device comprises: an upper support 5, a connecting device 4, 8 bolts 6, a lower support 1, a liftable hydraulic telescopic device 2 and a concave inclined plate 3 in the middle. When simulating rip current in a towed pool, first install the device on the central side bridge of the trailer, start the wave generator on the other side of the pool, input waves of different amplitudes and wavelengths, and the resulting waves hit the sloping plate , the wave flow on the inclined plate converges to the low-lying part of the inclined plate to form a backflow, and the backflow quickly returns to the pool, thereby realizing the simulation of the rip current.
[0021] The device can change the inclination of the inclined plate thro...

The invention belongs to the technical field of fluid mechanics of a towed pool, and in particular relates to a method and device for simulating offshore flow in a pool, which consists of a lower bracket, a liftable hydraulic telescopic device, a concave sloping plate in the middle, a connecting device, an upper bracket, and bolts , the upper surface of the lower bracket is fixed with a liftable hydraulic telescopic device, one end of the concave inclined plate in the middle is hinged with the lower bracket, and the lower surface of the concave inclined plate in the middle is fixed to the upper part of the hydraulic telescopic device that can be lifted. Together, the lower bracket is fixed with a bracket perpendicular to the lower bracket at one end hinged away from the inclined plate in the middle depression. The invention has a simple structure, is easy to install, and can realize the simulation of offshore currents. The device can meet the size of offshore currents in different degrees, and can conduct controllable research on offshore currents, and can better study the flow velocity and flow of offshore currents. Field characteristics, using PIV fluid testing technology to test and study the fine flow field of offshore currents.
Description
technical field [0001] The invention belongs to the technical field of fluid mechanics of a towed pool, and in particular relates to a method and a device for simulating offshore flow in a pool. Background technique [0002] Rip currents are ubiquitous on the seashore, and because of the existence of rip currents, people on the shore are in danger. The so-called rift current, also known as the rift current, is a narrow and strong water current like a beam. It flows to the outer sea in a direction perpendicular or nearly perpendicular to the coast, and the backflow caused by it can take people swimming in the water with them. into the sea and cause danger to life. The offshore current has been studied before, and the performance prediction and safety rescue of the offshore current are carried out. In order to study the flow state of the offshore current and the movement mechanism of the fluid more accurately, the fine flow field analysis of the offshore current is carried ou...
