NumericalSimulation of the Unsteady Aerodynamic of Wind Turbine under Yaw Condition

摘要

To be able to more accurate analysis aerodynamic characteristic variation underyawof NREL Phase VI wind turbine. The influence of yaw on the aerodynamic characteristicby usinga three-dimensional unsteady CFD methodsbased sliding meshin this paper.To flow, the overall performance and Cp of the three-dimensional flow numerical simulationwere compared with experimental results with the same wind speeds to confirm the reliability of the model at a given axial wind speed conditions.In the yaw conditions, the effect of yaw on the aerodynamic performance of wind turbine blades, changing law and reveal the aerodynamic performance is in the flow details and rules in different azimuth.
