摘要：

通过简化二维模型，建立一维模型，对两相泡状、上升、层流问题数值模拟，讲解两相流数值模拟分析问题、建立方程、离散方程的过程。问题典型，代码简练，计算结果符合实际现象，易于在较短课时完成讲授，有利于学生形成分析问题、求解问题的整体思维，帮助他们过渡到二维、三维问题的学习、研究开展。

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.
