This project studied the potential for installing roof-mounted vertical wind turbine (VWAT) several types of VAWM, blades with the goal of maximizing the efficiency of a shrouded turbine. Vertical axis wind mill power generation equipment can be located at ground level, which makes for easy maintenance. Also, VAWM are Omni-dimensional, meaning they do not need to be pointed in the direction of wind to produce power. The main objective of our work is to design and analyse a self-starting vertical axis wind turbine by using CATIA & ANSYS. It was concluded that a profile with large lift at low speed used along with passive pitching could achieve self-starting status. As a result, three blade profile were tested and compared over the testing in the wind tunnel and the blade profile that offers the best performance for self-starting
