摘要
为消除取水前池的水流在扩散过程中产生的回流、旋涡 ,提出了在前池中设置多组底坎的措施 .对设置底坎前后的复杂流动进行三维紊流数值模拟计算 ,并通过物理模型试验加以验证 .计算结果和试验结果十分吻合 ,有效地消除了回流和旋涡 ,流态显著改善 .
The paper brings up the Combined-sills are made in the forebay to eliminate the circulation and vortex of the diffusing flow. Numerical Simulation of three-dimensional turbulent flow is applied to the complicate flow before and after sills. The results are validated by the hydraulical model test. The computational results are in good agreement with the experimental data. The flow pattern is obviously improved. The Combined-sills has been successfully applied to the pumping project.
