Description

technical field [0001] The invention relates to a model test of fluid mechanics, in particular to an intelligent self-adaptive diversion device and a diversion method for a wave-current test pool. Background technique [0002] The wave pool simulation system is one of the effective methods to simulate the complex and changeable waves and currents in nature. Waves and currents are the main loads in port coastal engineering and ocean engineering. It is necessary to understand the effects of waves and currents in the planning, design and construction of ports, coasts, and ocean engineering. At present, there are three commonly used methods to understand wave current loads: field observation, physical model test and numerical simulation. But so far, some practical problems cannot be solved purely by mathematical methods, and on-site observation is difficult to achieve, so the simulation of wave flow pool has become an effective and reliable method. [0003] In order to form a ...

Problems solved by technology

These two situations are not conducive to creating uniform and stable inflow conditions. In actual operation, it is often necessary to accurately simulate various working conditions, that is, to achieve stable and uniform outflow under different combinations of water depth and flow velocity. , it can be seen from the above discussion that neither the fixed inflow boundary nor the fixed deflector can meet the actual demand
