| 中文摘要: |
| 本文利用κ-ε 紊流模型模拟坝面上的复杂紊流流场，并且采用非结构网格来处理复杂的边界形状，对自由水面，引入水-气两相分层流理论中的流体体积分数法（VOF）来迭代求解。通过模拟计算，得到坝面水流的水面线、速度场、压力场等，并与模型试验实测结果进行对比分析，两者吻合较好。 |
| 英文摘要: |
| The κ-ε turbulence model is applied to simulate the complicated turbulent overflow in the surface of stepped spillway.The non-structure grid is used to treat the irregular boundary and the volume of fluid method (VOF) for water-air two-phase flow is introduced into the iteration of calculation.The curvilinear free surface,velocity and pressure distributions are obtained.The calculated result is good agreement with the experimental data. |
