流动相似性原理是流体力学教学的重要内容。对流动控制方程进行无量纲化,从理论上推导出动力学相似条件,再用CFD技术对简单流动问题进行数值模拟,以对动力相似条件进行验证。从理论和实践两方面帮助学生学习较为抽象的动力学相似条件,以期取得良好的课堂教学效果,提高学生解决实际问题的能力。

The flow similarity principle is an important part in fluid mechanics.The dynamic similarity condition is derived from the non-dimensional governing equations of the fluid flow.Thereafter,in order to show the necessity of the dynamic similarity condition,a simple fluid flow is simulated using CFD technology.This method can help theoretically and practically students to study the dynamic similarity condition which is more nonfigurative.Good teaching effect in classroom can be expected.In addition,the ability of students for solving engineering problem can be improved.
