| Abstract: | It is important for micrositing a wind farm to master the distribution of wind energy in a complex terrain.For applying modern CFD in the simulation of wind flow over complex terrain, three typical geometries were selected for numerical simulation.The numerical results were validated by comparing with the experiment data.Effect of mesh and turbulent model on the vortex position and velocity distribution were analyzed.Discussion on how to determine the best position for setting wind turbine for increasing wind power attraction was made. |
