Abstract

Turbulent wind flow over complex terrain is very important for wind energy exploitation. In the present study, the flow characteristics over two-dimensional plateaus were studied in atmospheric boundary layer (ABL) wind tunnel through PIV measurements. The effects of windward and leeward slopes on turbulent flow characteristics were studied. The results indicates that the flow velocity decreases upstream of the windward side compared with the undisturbed flow, as the block effect of plateau. A flow separation takes place as the slope is steep, and the effect is far downstream of the plateau. The effects of slopes and steps are not evident, with the main difference occurring near the ground.
