采用ＶＯＦ方法成功地模拟出了含有各种复杂进、出口流边界及各种障碍物的三维液面波动，并可用部分单元体法求解任意形状容器内含自由液面的液体运动。针对影响快堆钠池液面波动的各种因素，可给出不同工况下液面的波动形状、钠浪波动的最高位置和最低位置以及钠浪涌的量级。本文提供了ＶＯＦ数值方法的主要原理，在ＮＡＳＡＶＯＦ３Ｄ的基础上开发了计算分析程序，及快堆钠池液面波动的部分计算结果。
The VOF method was used to simulate the 3D surface fluctuation with various complicated inlet and outlet flow boundaries and various obstructions. The solution of liquid with free surface in arbitrary shape can be solved by the partial element method. In view of the various factors that affect the liquid level fluctuation of the sodium pool in the fast reactor, the fluctuation shape of the liquid surface, the highest position and the lowest position of the sodium wave fluctuation, and the magnitude of the sodium surge can be given under different conditions. In this paper, the main principle of VOF numerical method is provided. Based on NASA-VOF3D, the calculation and analysis program and the partial calculation results of liquid level fluctuation of sodium pool in fast reactor are developed.
