When wind turbines are installed in wind farm, the site design is important. However recently wind measurement using meteorological masts and anemometers needs a lot of cost for large wind farms and large wind turbines. Therefore, a numerical analysis is used for the wind potential prediction. Good wind condition sites in Japan concentrate in mountain region. Wind profiles are influenced by not only the topography of the site but the ground roughness, and the consideration of the ground roughness influences is necessary for accurate simulation of flow fields. In this study, a numerical analysis of flow field around 2D hill model with different terrain shape and ground roughness models is conducted. The numerical analysis employs standard k-s model, and analyzes steady-state model. The effect of terrain shape and ground roughness on the flow field is discussed and proved.
