A Comprehensive Experimental Flume for Studying Seabed Wall Effect

Abstract

The invention discloses an integrated test water tank for researching the seabed ground effect. The integrated test water tank comprises a water tank body, a wave generation device, a flow generationdevice, a dragging and self-rotation measurement device and a ground bed bottom simulation device; the wave generation device is provided with a wave generation plate, which can move in the water tankbody in a reciprocating manner; the flow generation device is provided with a water inlet pipe, which can spray water in the water tank body; the dragging and self-rotation measurement device is provided with a suspension rod, which can move and rotate in the water tank body; and the ground bed bottom simulation device is provided with a separation plate, which is arranged along the length direction of the water tank body and can transversely move in the water tank body. The integrated test water tank for researching the seabed ground effect in the invention has the benefits: due to the meansof adjusting the distance between a test model and a smooth transparent plate, changing water flow parameters and the like, the purpose of simulating influence of different hydrodynamic characteristics of the near ground on movement of an underwater vehicle can be realized.

Description

technical field [0001] The invention belongs to the technical field of hydrodynamic detection, and in particular relates to a comprehensive test tank for studying seabed wall effects. Background technique [0002] In the past two decades, a large number of underwater robots have appeared in response to the needs of ocean development and utilization and underwater engineering applications. In the underwater operation project of the robot, an important task type involves the underwater operation in the environment near the wall. When the underwater robot works on the surface of the structure, there will be an obvious wall effect (Ground Effect), which will cause a significant change in the flow field around the structure wall, resulting in the failure of the normal control mode of the underwater robot. When the characteristic clearance ratio of the wall surface and the vehicle body scale In this case, the flow field is more complex and has high-viscosity flow characteristic...
