Problems solved by technology

For the simulation of deep water flow in marine engineering pools, the former cannot directly measure the section, but can only measure the flow velocity at certain points, and the measurement accuracy of the latter is difficult to meet the test requirements
[0003] At present, there is the "Langlong" measuring profile velocity meter produced by Norwegian Nortek (NORTEK CN) company. This equipment is mainly used in the measurement of offshore and coastal velocity. Meet the measurement requirements of fixed-point flow velocity in marine engineering pools, profile flow velocity along the depth direction of the pool, and flow velocity distribution in the three-dimensional flow field of the entire pool

Description

technical field [0001] The invention relates to a deep-water flow velocity measurement system, in particular to a deep-water flow velocity measurement system for marine engineering pools used in ocean deep-water model tests. Background technique [0002] With the continuous development of scientific research work in the field of ocean engineering, ocean engineering model tests have become an important part of ocean engineering scientific research. The requirements for the technical difficulty and precision of ocean engineering tank tests are getting higher and higher. The simulation accuracy of the marine environment such as wind, wave, and current directly determines the accuracy of the ocean engineering test. Therefore, marine engineering tests put forward higher requirements for the methods, methods and accuracy of wind, wave and current marine environment simulation measurement. In particular, deep water current measurement is more difficult. At present, there are two...
