摘      要：In this study,the performance of a contra rotating vertical-axis tidal-current turbine was *** incompressible unsteady Reynolds-averagedNavier-Stokes(U-RANS)equations were solved via two-dimensional(2D)numerical simulation using ANSYS Fluent computational fluid dynamics(CFD)*** algorithm known as SIMPLE from the CFD code was used to calculate the pressure-velocity coupling and second-order finite-volume discretization for all the transport *** base turbine model was validated using the available experimental *** given scenarios for the contra rotating turbine were *** contra rotating turbine performs better in a low tip speed ratio(TSR)than in a high TSR *** a high TSR operation,the contra rotating turbine inefficiently operates,surviving to rotate in the chaotic flow ***,it is recommended to use contra rotating turbine as a part of new design to increase the performance of a vertical-axis tidal-current turbine with a lower TSR.
