In small-scale hydropower scheme, the most important component is electro-mechanical equipment. Since cost contribution of this component is high because hydrokinetic projects require negligible civil works. Turbine and alternator contribute a major fraction of the hydrokinetic projects. Thus, there is a requirement to estimates the electromechanical equipment cost for a hydrokinetic hydropower...

Wind generation is an alternative to energy that renewable, widely distributed, and environmentally friendly. However, the use of wind in certain areas with limited land has constraints for installing large-scale generators; therefore, concept micro attractive solution be developed at this time. In case, Vertical Axis Turbine (VAWT) preferred because it reliable economically feasible operate lo...

In order to improve the efficiency of Savonius type vertical axis wind turbine, present work analyzes an improvement based on innovative rotor geometry. The blades are inspired organic shape mathematically analyzed, Fibonacci’s spiral, presented in many nature systems as well art. This was analyzed a tunnel and through CFD model. power coefficients at different tip speed ratios (TSR) were chara...
