摘要
依据RNGk-ε双方程紊流模型,并采用VOF方法追踪自由水面和笛卡尔网格法处理复杂几何边界,对汤河水库溢洪道弯道水流进行了三维数值模拟,得到不同流量下溢洪道弯道的自由水面线、压力分布以及流速等流场参数分布规律。
Based on two-equation turbulence model of RNG ,and using VOF method to track the free surface and the Cartesian grid method to deal with complex geometric boundaries ,Tanghe Reservoir spillway flow curve dimensional numerical simulation were obtained free water distribution line of different flow under spill-way bend,pressure distribution and flow field parameters distribution law.
