Vertical Axis Wind Turbine Simulation Jarrett Johnson ET 494 – Senior Design II Advisor: Dr. Junkun Ma Instructor: Cris Kutsougeras

Objectives • Design vertical axis wind turbine and determine how blade will rotate • Specify dimensions for 1020 airfoil to be used in the design • Build geometry in Comsol • Calculate pressure distribution of wind across airfoil • Calculate pressure distribution of wind across airfoil with wind blowing at different positions/angles • Simulate design and record data to optimize efficiency of the system
