In present study a helical Savonius wind Turbine is studied in a 3-dimensional flow domain with the help of a simulation Software with main focus on value of static torque coefficient of a helical Savonius wind turbine. A 3D model of helical Savonius turbine with 900 twist and without shaft is developed and simulation is carried with the help of Ansys Fluent solver. The numerical results were obtained by solving incompressible steady flow equations with the help of k-ɛ Realizable turbulence model. Static pressures on turbine blades are obtained and Static torque Coefficient is calculated at different rotor positions. The simulation results are compared with experimental results available in literature. It is observed through numerical study that at certain rotor positions the value of Cts is negative. Further efforts are made to find out the reasons for the negative values of Cts. The above study was done at different wind velocities and results are presented.
