Abstract

A new numerical algorithm for simulating transonic flows of nonreacting gas mixtures is proposed. The algorithm is based on the finite volume method as applied to regularized, or quasi-gasdynamic, equations. The equations describing multicomponent gas flows are derived phenomenologically using an existing regularized system for one-component gas and classical equations for gas mixtures. The numerical examples include the computation of the nonstationary interaction of gas flow with heavy and light gas bubbles.

基于拟气动力学方法的混合气数值模拟在冲击波与气泡相互作用中的应用

摘要

提出了一种模拟非反应混合气跨音速流动的新数值算法。该算法基于应用于正则化或准气体动力学方程的有限体积方法。使用现有的用于单组分气体的正则化系统和用于气体混合物的经典方程式，从现象学上导出描述多组分气体流量的方程式。数值示例包括气流与重气泡和轻气泡的非平稳相互作用的计算。
