“…Chen Jianping evaluated the quality of the flow field in the test section of the CWC high-speed free-surface circulating water channel [8]. Abroad, A M Santos used PIV to evaluate the scope of application of circulating water channel [9]. FD Felice used PIV to measure and analyze the wake in the longitudinal plane under the rotation angle of the propeller based on the INSEAN circulation water channel [10].…”

The flow field quality of the super high speed circulating water channel (SHSCWC) test section in the open (with a free liquid surface state) and closed (with a cavitation tunnel state) was studied. An array of flow field measuring points was established to measure the axial velocity using a laser doppler velocimeter (LDV) for both states. Meanwhile, ultrasonic sensors were used to measure the levelness of the free liquid surface in the test section. The measurement results indicated that in the open state, the non-uniformity and instability of 8 kinds of flow velocity in the flow field section are less than 1.0%, respectively, while the free liquid surface level is less than 25mm at the flow rate of 8m/s. In the closed state, the non-uniformity and instability of eight types of flow velocity in the flow field section are all below 1.0%, with turbulence being less than 0.5%. The measurement results in both states meet the requirements of technical indicators, and provide data support for the experimental research and optimal design of the SHSCWC.
