| Abstract: | Different deepwater vertical current profiles are simulated by using CFD software.And some analyses have been made,such as the dimensional flow uniformities and turbulence levels.The velocity of flow is also compared to the targetone.Compared with model test results,it is shown that the results of the simulation are reliable,and the current generation system is able to simulate different vertical current profiles,which satisfies the simulation requirement of the deepwater current in the basin. |

| Keywords: | vertical current profile measuring area turbulence intensity numerical simulation |
