Abstract

Wind characteristics over local topography after a wind turbine are studied through Wind Tunnel Experiment. Results are used for validating data for the CFD prediction of the airflow through a wind turbine. The major results are as follows. 1. Characteristics of leeward wind velocity of a single wind turbine model show the characteristics of wake flow after the flow obstacle. 2. The influences of the wind turbine model become smaller with distance from the wind turbine to the downward direction. 3. Significant differences were observed in the drag coefficient of wind turbine model, when the various arrangements of wind turbines were set before the objective model.
