To gain a quantitative understanding of the interaction mechanism, the flow field surrounding two closely spaced Savonius turbines at different oblique angles is computationally examined. The mutual interaction among Savonius wind turbines enhances the electrical output of individual turbines, and thereby benefits the overall power of the turbiness. A two dimensional wind-driven free rotation analysis is modeled using shear stress transport (SST) k-ω eddy viscosity model for the closure of turbulence in a overset mesh topology. The computational findings of the conventional Savonius turbine are verified integrating benchmark experimental data and that functions as a scale for the forecasting portion of mutual coupling. The mutual coupling effect is analyzed based on the gap distances (S) and varying oblique angles (θ) for two co-rotating Savonius wind turbines. Oblique angle α = 50º demonstrates an ideal value of coupling affect practicable with a percentage increase of 33.81%.
