摘要
本文用矢通量分裂法求解了瞬态两相流问题.首先导出了瞬态两相流控制方程的特征根,然后将矢通量分裂成二个子矢量,使每一个子矢量仅包含一种符号的特征值,再利用空间的一侧差分,得到差分方程并求解,最后将数值预测与实验结果进行了比较,其结果十分吻合.
In this paper the transient two-phase flow equations and their eigenvalues are first introduced. The fluX vector is then split into subvectors which just contain a specially signed eigenvalue. Using one-sided spatial difference operators finite difference equations and their solutions are obtained. Finally, comparison with experiment shows predicted results produce good agreement with experimental data
