In order to get the real information of internal flow field in environment of ocean current, the paper used acoustic doppler velocimeter (ADV) to measure the velocities at fixed measuring points under three different groups of water discharge and drawn the corresponding figures of flow field, velocity and turbulence intensity in accordance with experimental data. By comparison of these figures,it analyzed the characteristic of ocean current produced by simulated current generation system.The result can provide valuable reference for the deep-water experiment and simulation of practical engineering in the future.
