【摘要】 为了详细了解黑龙江干流松花江汇口河段的水流流场情况,采用三维数学模型方法对松花江汇口段进行模拟研究。并引进水气两相流的VOF模型,与k-ε模型结合的方法进行计算模拟。数值求解采用SIMPLE算法的改进形式SIMPLEC算法。网格划分则采用了非结构化混合网格以增强对复杂边界的自适应性。更多还原

【Abstract】 The flow field of the confluence reach of Songhua River into main Heilongjiang River is simulated with 3-D mathematical model herein,and then a calculating simulation based on the combination of both the VOF model and the k-ε model for air-water two phase flow is also made.The numerical solution is carried out SIMPLEC algorithm modified from the algorithm of SIMPLE.Moreover,the non-structural and hybrid grids are adopted for the grid division,so as to increase the self-adaptability against the complex boundary concerned.更多还原
