摘　　要：针对追踪溃坝洪水自由面变化一直为计算流体力学的难点问题,采用Youngs-VOF方法追踪流体流场自由面、交错网格离散求解区域、人工压缩方法求解粘性不可压缩流体控制方程,并通过数值计算模拟了溃坝洪水瞬变现象。结果表明,Youngs-VOF方法追踪运动交界面与MARTIN的试验结果吻合,且略优于Hirt-VOF法,为溃坝洪水的模拟提供了新途径。Free surface tracking in process of dam break flood is always difficult problem in computational fluid dynamics.Youngs-VOF method is used to trace free surface of flow filed.Staggered grid is adopted to discrete solution domain.The viscous incompressible fluid control equations are solved by using artificial compression method.The transient phenomenon of dam break flood is simulated by numerical calculation.The results show that moving interface tracking with the Youngs-VOF method is consistent with the MAR...
