主题：两相流动，理论与方法的数值分析

Topic: Numerical analysis on two-phase flow; Theory and method

内容简介:

两相流问题是科学与工程领域中一个非常普遍的问题。该问题的数值分析从20世纪80年代开始，在计算应用中得到了迅速的发展。处理两相流有两种主要方法;拉格朗日和欧拉方法。这节课将从两相流的基本概念和处理方法开始。介绍了两相点火和爆轰计算的一些典型实例。

Introduction:

Two-phase flow problem is one of very popular problem in science and engineering field. The numerical analysis of the problem has been started 1980s and has been developed quickly in computational application since then. There are two major ways to take care of two-phase flows; Lagrangian and Eulerian method. The lecture will start with a fundamental idea of two-phase flow and a method to deal with it. Some typical examples of two-phase ignition and detonation calculation will be presented.
