Optimization Technique for Hydrokinetic Turbine Blades: Pressure Minimization Approach

Abstract

Everyday rise in world population push for more energy demand. The dependence and usage of fossil fuel in an uncontrolled manner has triggered environmental imbalance. A need to discourage the use of fossil fuel birth renewable energy is a form of energy which is not just environmentally friend but relatively cheap. Hydrokinetic turbine is a device which extracts kinetic energy from moving water to generate power. Hydrokinetic blade is an integral part of hydrokinetic turbine which is one of the components that determines the output power. There is power loss during the operation of the turbine and there is need to reduce this loss. This gives rise to a need to develop an optimization technique that can optimize turbine blade in addition to the existing models. Parameters concentrated on include pressure coefficient, axial induction factor, tangential induction factor, local tip speed ratio and angle of flow
