Abstract: Crossflow wind turbine is vertical axis wind turbine that has high coefficient of power (Cp). The simulation aimed to understand the effect of blade thickness and blade number of vertical axis wind turbine with cross flow runner to enhance the performance of wind turbine. The turbine had 2.6 mm; 10 mm; 15 mm; and 20 mm blade thickness, and 18, 20, and 22 blades number. Simulation was done in two-dimensional analysis using ANSYS-Fluent. Tip speed ratio was varied in the range of 0.1 to 0.5 with constant inlet velocity of 2 m/s. The effect of blade thickness and blade numbers to torque and coefficient of power were analyzed and compared. It has been found that the highest coefficient of power was 0.5 at tip-speed ratio of 0.2, blade maximum thickness of 20 mm and blade number of 22.
