摘　　要：采用LBM对流体力学教学中的经典案例进行了数值模拟,并基于Matlab GUI工具对其进行封装,开发了流体力学虚拟实验仿真平台。该仿真平台主要包含3个案例模块:顶盖驱动流、泊肃叶流和卡门涡街模块。学生可在用户界面上输入工况参数进行计算,并获得计算结果的直观展示。相对于流体力学传统教学方法,本虚拟仿真实验平台具有可视化效果好,计算速度快,界面清晰操作简单等优点,有助于加深学生对抽象概念与理论的理解认识,容易激发学生的学习兴趣和提高教学效果,值得在流体力学教学中进行推广。Aiming at enriching teaching contents and experimental teaching methods of fluid dynamics course,several classical problems in fluid mechanics have been simulated using LBM(Lattice Boltzmann method).An integrated virtual simulation experiment platform encapsulated by Matlab GUI(Graphic User Interface)is developed to improve traditional teaching mode and teaching efficiency.Three modules,lid-driven flow module,Poiseuille flow module and Karman vortex street module,are included in this platform.The simulation results can be displayed directly by inputting operating parameters on the user interface of the platform.Compared with the traditional teaching mode and experiment,this integrated virtual simulation experiment platform has the advantages of good visualization,fast calculation speed,clear user interface,simple operation,low teaching cost and easy communication,which is beneficial to the understanding of the students on the abstract concepts and complex flow patterns in fluid dynamics course.Owing to the increase in the interest of the students and the efficiency of classroom teaching,this platform deserves to be popularized in the teaching of fluid mechanics.
