The flow field of a marine current turbine(MCT) with single rotor was simulated based on large eddy simulation(LES) and Spalart-Allmaras(SA) turbulence model in order to predict the hydrodynamic performance of MCT with dual rotor.The performance of the MCT was obtained and compared with the experimental results.Results show that both SA model and LES model can well predict hydrodynamic performance.The flow field of MCT with dual rotor in tandem arrangement was simulated with LES model.The influence of the distance between two rotors on the performance of the MCT was analyzed.Results show that the performance of downstream rotor is greatly affected when the distance between two rotors is less than 5 times of rotor diameter.In order to keep a high performance for the MCT,the distance should be over 30 times of rotor diameter.
