摘要
本文采用双方程紊流模型对中孔窄缝消能工的出流进行了三维紊流数值模拟,给出了侧墙压力分布、流场、挑流水面线等水流特性。计算结果和模型试验数据对比,两者吻合较好,对不同底板挑角的方案进行的比较计算结果,发现底板挑角对水流特性有着明显的影响。
The k-ε two-equation model for turbulent flow is applied to numerically simulate the 3-D flow formed by slit-type energy dissipaters for mid-level outlets. The pressure distributions on sidewalls, flow field and water surface of the nappe are in good agreement with the results of model test. It is found that the flow characteristics are remarkably varied with the angle of emergence of the bucket.
