摘要
该文将CE／SE方法从气相流拓展到两相流,构造了适合内弹道两相流动的计算格式,并将之应用于内弹道膛内双一维两相流动的数值模拟中。源项采用四阶Runge-Kutta方法进行处理;与传统的MacCormack格式相比,采用CE／SE方法对膛内两相流计算无需添加人工粘性。用该方法得出的计算结果符合实际过程,与实验结果一致,说明采用此方法进行内弹道两相流计算是可行的。
In this paper, the numerical method of the space-time conservation element and solution element （CE/SE） is extended to a two-phase flow from a gas flow, The computational method to solve the two-phase flow in guns is constituted and applied to the numerical simulation on the double one-dimensional two-phase flow in guns. The source items are calculated by the fourth-order Runge-Kutta method. Compared with the traditional MacCormack method, the artificial viscosity is not necessary in the computation of the two-phase flow in guns with CE/SE method. The computational resuits from the method are consistant with the practical process and the experimental data, and show that the CE/SE method can solve the two-phase flow in guns.
