The RNG k-ε turbulence model and VOF(Volume of Fluid) method are employed to numerically simulate the flow pattern in the grid-suspended plunge pool of the diversion tunnel outlet of Wuyi Reservoir.The computation results of the water depth along the way,the pressure on the bottom and velocity of the grid-suspended plunge pool are in agreement with those from experiments and measurements.The simulation of flow pattern could overcome the shortages of physical model test and provide references for practical engineering design.
