The blade shape is a critical factor in designing Savonius turbines for maximum efficiency. The blades of a Savonius turbine are curved, which can create turbulence and reduce the turbine's performance. However, optimizing the blade shape can increase the energy generated by the turbine. There are two primary blade shapes used …
