Analysis of Venturi Wind Turbine for Domestic Purpose

The energy from conventional sources has its limitation hence there is need to harness Energy from non-conventional sources. The purpose of the project is to ensure the raise in speed of wind turbine blades by increasing the wind velocity specially for low wind speed area where the average speed of wind is 1.5 m/s. In Venturi Wind Turbine the air comes from inlet section with less velocity, it flows from venturi passage. Due to continuous reducing area of cross section of venturi the pressure drop takes place. At the Throat the velocity of air is maximum, this wind then strikes on blades of Turbine, so blades moving with highest speed. The main advantage of the project is we can install the venturi on smaller windmill which are used for household application and we can install this system even where the wind velocity is less. The analysis of venturi wind turbine is done by CFD. The analysis gave indication that the velocity of turbine is increased because of venturi.
