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。In this paper,two-phase bubble,rising and laminar flow problems are numerically simulated,and the process of twophase 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.
