摘要

摘要: 采用标准双方程k-ε紊流模型和VOF方法建立二维数值模型,模拟有横流情况下底部排污问题.将回流区的分析结果与试验进行了对比,吻合较好.分别将速度和浓度轨迹线拟合成简单的表达式并与试验拟合作了比较.通过对速度和浓度场的分析得到一些有益的结论.

Abstract: A two-dimensional bottom jet discharged into a cross-flow is simulated by the standard two-equation k-ε model with VOF method.By comparing with experimental results,it is shown that the recirculation zones calculated using the model generally agree with the experimental results.Velocity and concentration's trajectories are expressed by simple form ulas and compared with experimental results.Some conclusions are also draw by analyzing the velocity and concentration distributions.
