Abstract—The performance of hydrokinetic turbines of Savonius using a Tandem Blade Savonius (TBS) rotor was studied. These were three types of TBS: Overlap (Type I), Symmetrically (Type II) and Convergence (Type III). Through a comprehensive bibliographical research, it is possible to identify the influenced parameters, and to show that the optimum efficiency of the Savonius rotor can be particularly improved their partition space between blade and tandem. This simulation shows the way of the flow characteristic and pressure distribution pattern in and around of the blade swept area. The results show that the convergence TBS (Type III) have a higher gap pressure between upstream and downstream, or they have best performance than other types.
