Abstract:In this paper, work performance of Tocardo-type turbine is numerically investigated by using BEM method. Tocardo-type turbine is significantly different from lift-type turbine in which it owns long chord and thick blade and it is of bidirectional characteristics. Working performance of Tocardo-type turbine is obtained by using BEM method and the results release that it is not of lift-type turbine because the parameter of Cl/Cd is not chosen as maximum value. Compared with the performance of lift-type turbine, working coefficient of Tocardo-type turbine is little lower at optimum working condition. The results also show that the optimized tip speed ratio of Tocardo-type turbine is about 4.5 and working power reaches about 183kW as coming velocity is 4m/s.
