摘要：
The 3-D flow fields in the plunge pools of the Xiaowan high arch dam and Laxiwa high arch dam in China are simulated by the turbulence mathematical model and measured by the five-hole Pitot sphere combined with the pressure sensors and automatic data sampling and processing system. The typical 3-D flow pattern and energy dissipation characteristics in plunge pool are obtained. The simulated results of energy dissipation show that the water body in plunge pool can be divided into three regions: shear, impact and mixing dissipation regions of energy.
