The experimental results indicated that,under the windward and leeward conditions,the cooling effect of crushed rock revetments with all these four grain-diameters was good and could effectively reduce the temperatures of the underlying soil layers;furthermore,the mean pe.

This paper sets up the wind speed model considering wake effect only using the available parameters and data of wind farm and turbines within the park according to the shadow of the upstream wind turbines to the downstream turbines and variable shadow size at some wind direction after analyzing calculation method of leeside wind speed.
