The design of the turbine will include exploration of various self-starting options, as well as the construction of both mode land full- scale turbines. The full-scale turbine will be designed such that it can be connected to a generator and a torque transducer to measure the output power, torque and rotational speed of the turbine. The design will also allow for data collection regarding the effects of blade pitch angles. Here compare both experimental and simulation analysis by using CFD and As a result of the engineering analysis carried out for the NACA 0012 and it had been designed in design software Catia and the flow analysis was carried out in CFD by using Fluent and CFX software.

INTRODUCTION The main objective of the project is doing improve the output of the wind power generation produce electric power using a vertical axis wind turbine, Currently, horizontal axis wind turbines (HAWT) dominate the wind Energy market due totheir largesize and highpower generation characteristics. However, vertical axis wind turbines (VAWT) are capable of producing a lot of power and offer many advantages. The mechanical power generation equipment can be located at ground level, which makes for easy maintenance. 2. INTRODUCTION TO CFD CFD is a technique of replacing Partial Differential Equations governing the fluid flow by a set of algebraic equations and solving them using a digital computer. Any fluid flow in the universe is governed by a set of equations. The equations are the governing equations, • Continuity Equation. • Momentum Equation. • Energy Equation. Governing equations in partial differential form 2.1. Continuity Equation The continuity equation in algebraic form is given as ρ1 A1V1 = ρ2 A2V2 The continuity equation in integral form is given as,    + .  = 0
