A review investigation of the Savonius hydrokinetic turbines: application an optimization

In recent years, due to the energy crisis, the attention of researchers and energy industry experts has been drawn to the use of renewable energy sources. Among renewable energy sources, hydroelectricity is of great importance due to its major advantages, such as its widespread distribution on the earth's surface. Studies have shown that hydrokinetic energy can be a suitable alternative to fossil fuels. Savonius turbines are one type of turbine that, when combined with hydrokinetic systems, will produce clean and accessible energy. The Savonius vertical wind turbine must be started non-automatically. Additionally in Savonius wind turbine slow speed reduces productivity and increases costs. When this turbine is used in a flowing water, its characteristics will change and need to be optimized. Accordingly, numerous studies have been conducted on the optimization of these turbines. Accordingly, this article will review and investigate published articles in this field. It also describes how each of the effective parameters affects the performance of these systems.
