Numerical Assesment of a Small-Scale and Very Low Tip Speed Ratio Wind Turbine

The aim of this paper is to study by CFD the performance and to characterize the velocity fields in the wake of an horizontal axis wind turbine. The design of this wind turbine is far from classical as it has been designed to work at very low angular velocity to promote torque. The 8 blades are not...
