| Abstract: | To determine reasonable boundary conditions for the reconstruction of boundary layer flow over complex terrain,a downscaling approach was proposed by coupling the mesoscale numerical weather prediction(NWP)and the microscale computational fluid dynamics(CFD).Solutions derived from NWP models were utilized as the initial input for the CFD simulation by inverse distance weighted(IDW)interpolation.Strong wind events occurred in two actual wind farms with complex terrain were employed to test the performance of this downscaling approach.The applicability of IDW methods in data transferring process had been validated by the empirical profiles of wind.By comparing with the on-site data at observing towers,the downscaling performance had been evaluated by error statistics method.The results illustrate that the coupling approach proposed in this paper can effectively reflect the wind field distribution for small-scale wind turbines considering topographic features. |
