2D Numerical Simulation and Sensitive Analysis of H-Darrieus Wind Turbine
International Journal of Renewable Energy Development, 2018 Recently, a lot of attention has been devoted to the use of Darrieus wind turbines in urban areas. The aerodynamics of a Darrieus turbine are very complex due to dynamic stall and changing forces on the turbine triggered by changing horizontal angles. In
