摘　　要：基于贴体坐标转换和有限体积法,用k-ε两方程模型模拟水体的运动,在同位网格上使用动量插值法避免了压力的波动。建立了冰塞面的变形方程,并用C语言编写的程序对冰塞堆积进行了数值模拟计算,对比实验室中冰塞堆积试验的结果,两者的吻合较好。Based on transformation of body-fitted coordinate system and finite volume method the k-ε two-equation model was used to simulate the flow field under the ice cover.To avoid the pressure oscillation in the non-staggered grids,the momentum interpolation was introduced to calculate the interpolation at the interface.An equation describing the deformation of ice jam bottom was developed and the computational program in C language was developed to numerical simulate the accumulation of ice jam.The simulation re...
