Abstract: 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.

Key words: numerical simulation, fluid mechanics, experimental teaching, Bernoulli's experiment
