摘　　要：为强化学生对流体力学课程理论知识及实验教学环节的掌握,本文针对传统实验教学过程中受限于硬件设施、模型等问题,将数值模拟技术与流体力学实验教学相结合。以伯努利实验为例,应用数值模拟软件进行物理建模、网格划分、变参数数值模拟等实验内容,通过压力云图、流线等模拟结果对能量转换特性进行了分析,增强了学生对流体力学理论知识及相关参数的物理意义、变化特征等的理解,使学生在实验中产生强烈的“参与感”,有效地提高了教学水平和教学质量。In order to strengthen students’mastery of theoretical knowledge of convection mechanics course and experimental teaching,this paper combines numerical simulation technology with experimental teaching of fluid mechanics,aiming at the problems limited by hardware facilities and models in traditional experimental teaching.With Bernoulli experiment as an example,the application of simulation software for physical modeling,meshing,variable parameter numerical simulation experiment content,etc.Through the stress nephogram and streamline simulation analyses the characteristics of energy conversion,to enhance the students’knowledge of convection strength theory and the related parameters of the understanding of the physical meaning and characteristics,so that the students in the experiment the intense“engagement”,effectively improve the teaching level and teaching quality.
