摘　　要：为了改善工程流体力学教学效果,将CFD数值模拟方法引入课堂教学中,通过介绍课程中的3个知识难点:模拟卡门涡街、突扩及突缩管流、液体随容器旋转等案例,阐述了边界层分离、流线、迹线、局部水头损失、伯努利方程、气液两相流等概念及原理,并进行相关案例拓展.实践表明,CFD模拟方法可用于解决课程知识难点,促进学生将理论和工程紧密联系,提高教学质量.In order to improve the teaching effect of engineering Fluid Mechanics,CFD numerical simulation is used in classroom teaching.Through the introduction of three knowledge difficulties in the course,simulated Karman vortex street,pipe flow with sudden expansion or shrink and the container rotation case,boundary layer separation,streamline,path line,local resistance loss,Bernoulli equation,gas-water two phase flow concept and theory are elaborated and some relating cases expanded.The practice shows that the CFD simulation teaching can be used to solve the difficulties in the course,to promote the close links between theory and engineering in the student’s study so as to provide reference for promoting curriculum teaching reform.
