To use wind energy resources for power generation,the wind turbines must be installed in high wind potential site.To estimate wind condition on complex terrain,such as Japanese topography,it is important to clarify the flow around complex terrain In this research,flow field over the two-dimensional hill is investigated experimentally in a wind tunnel with boundaiy layer profile and two lands of turbulence intensity.The flow around hill model is measured by PIV system.In addition,ground surface pressure is measured.This measurement clarifies the influence that turbulence intensity,hill slope angle and vegetation give in flow over the hill.As a result,the difference of turbulence intensity of inflow affects to shift separation point,reattachment point and ground surface pressure.
