Abstract

Renewable energy lately very popular and intensively conducted research as an alternative of the fuel energy that non-renewable such as petroleum, coal, natural gas inventory is depleted of its natural resources. Wind energy is able to fulfill most of the energy condtions of the world by its efficient conversion in to energy. As we knew wind turbine divide two types refer to shaft axis direction: the first Horizontal Axis Wind Turbine (HAWT) is recent popular but needs high wind speed to produce energy, and the other one Vertical Axis Wind Turbine (VAWT) only needs low wind speed and it can be installed anywhere which are some of the reasons for this research. The purpose of this study research is to improve the design and performance of VAWT to make it more safety, esthetics, efficient, durable and sustainable. For a VAWT blades perform the main function to extract energy from the wind. The aerodynamic of Airfoil is considered as the blade for this new design of VAWT. Airfoil has some good aerodynamic characteristics, match with the characteristics of Savonius type VAWT, such as good stall characteristics and little roughness effect, relatively high drag and low lift coefficient. Integration of Computational Fluid Dynamics (CFD) simulation and wind tunnel experimentation has made the current research more acceptable. 3-Dimensional CAD models of various simple airfoils have been designed in Unigraph (Autocad, Solidworks). Using these airfoils and other shape, CFD simulation has been performed with 8 (eight) different VAWT designed blades combination models. Moving mesh and fluid flow simulation have been developed in CFD software FLUENT 15. The findings of these numerical simulations provided pressure contour, velocity contour, drag coefficient, lift coefficient, torque coefficient and power coefficient for all these models. Physical models of NACA0015. By comparing the methode of numerical analysis it can be concluded that NACA0015 airfoil VAWT model gives the better prestation of performance on the low speed and at higher Tip Speed Ratio.
