| In order to strengthen the experiment teaching of fluid mechanics course, on the basis of analyzing nine main problems of fluid mechanics experiment teaching at present, this paper puts forward the necessity and new idea of developing computer fluid mechanics simulation experiment teaching. In order to facilitate the development and production of multimedia experimental simulation software combined with scientific research, 14 traditional and 4 modern fluid mechanics experiment projects are introduced in this paper, which basically covers the knowledge points of the course of hydrodynamics. Through the study and development of engine axial cooling fan performance computer simulation experiment, the method of using real machine experimental data fitting equation to generate simulation software experiment platform is expounded. Through comparison with experimental data, it is showed that the computer simulation experiment of fan performance is accurate. The practice proves that virtual simulation experiment teaching is a shortcut with practical significance. |
