Abstract:

In this paper， two-phase bubble， rising and laminar flow problems are numerically simulated， and the process of two-phase flow numerical simulation of problem analysis， equation establishment， and equation discretization are explained by simplifying two-dimensional model into an one-dimensional model. The problem chosen is typical， the code is concise， and the calculation results are in line with actual phenomena. It is easy to complete the teaching of this problem in a relatively shorter time， which is helpful for students to form an overall thinking of analyzing and solving problems， and helping them transit to the study and research problems in dimension 2 and 3.
