| 摘 要： | 本研究提出了一种基于浸入边界法（IBM）和流体体积法（VOF）的粘性二相流的数值模型。其中，IBM用于处理流体中的固体边界的影响，VOF用来捕捉自由液面。由于自由液面处流体的密度和粘性系数是变化的，所以，在流场控制方程中将密度和粘性系数也当作变量来处理。基于该模型，对带障碍物的溃坝这个经典的问题进行了数值模拟，并将数值模拟结果与其他研究者的试验及模拟结果进行了对比分析，验证了该数值模型的有效性和实用性。

| Abstract: | A viscous two-phase numerical model based on the Immersed Boundary Method (IBM) and Volume of Fluid (VOF) method has been employed. In this model, the direct-forcing IBM and VOF method are applied to present the rigid boundary and capture the free surface respectively. Due to change of density and viscosity on the free surface, the density and viscosity are regarded as variables in the governing equations. The feasibility and accuracy of model are validated by simulating the dam-break with an obstacle. The simulation results agree well with other researcher's simulation results and experimental observation. |
