开发了能模拟复杂紊流的三维数学模型，编制了大型计算程序，针对拉西瓦水垫塘进行了数值模拟，揭示了水垫塘内速度、压力、紊动能及其耗散率的三维分布规律。获得了详细的水垫塘流态特性。研究了水流紊动扩散及消能特性，反映出紊动和消能大量地发生在射流轴线附近，计算所得的底板最大冲击动压与实验值进行了比较，二者符合良好。
A three-dimensional mathematical model for simulating complex turbulence was developed and a large-scale calculation program was developed. The numerical simulation of Lhasiwa plunge pool was carried out and the three-dimensional distribution of velocity, pressure, turbulent energy and its dissipation rate was revealed . Get detailed plunge pool flow characteristics. The characteristics of turbulent diffusion and energy dissipation were studied. It was found that the turbulent and dissipative energy occurred in the vicinity of the jet axis in a large amount, and the calculated maximum impact dynamic pressure of the bottom plate was compared with the experimental data.
