对ＳＯＬＡＶＯＦ法进行了改进， 克服了传统的ＳＯＬＡＶＯＦ中的“施体受体”法在处理三维自由表面时易出现计算误差和时间步长小的缺点， 所建立的“三维施受体法”成功地用于充型过程中自由表面的数值模拟。在自由表面压力边界条件中采用新的压力插值函数， 解决了三维情况下因出现相互交叉或相互重叠的自由表面而导致的同一表面单元存在几个插值单元的情形， 用该插值函数不需确定自由表面的法向方向。
The SOLA-VOF method is improved to overcome the shortcomings of the “donor-acceptor” method in the traditional SOLA-VOF process when dealing with three-dimensional free surface prone to calculation errors and small time steps, the “three-dimensional Shi Reciprocal method ”was successfully used to simulate free surface in filling process. The new pressure interpolation function is adopted in the free surface pressure boundary conditions to solve the situation that there are several interpolation units in the same surface unit due to the emergence of mutually intersecting or overlapping free surfaces in three dimensions. The normal direction of the free surface.
