摘要 流体力学实验是资源循环科学与工程专业实验课程中的必修项目。在实验教学过程中,将流体力学的数值模拟技术与实验测试技术相结合,可以加深学生对流体力学理论知识的理解。以圆柱绕流尾涡流场可视化实验为例,利用基于COMSOL仿真软件开发的CFD模拟App,可完成物理建模、网格划分、变参数仿真等数值模拟内容,并可以通过流速云图、压力云图、流线图等模拟结果对卡门涡街脱落频率进行分析,从而增强学生对流体力学理论知识及相关参数物理意义、变化特征的理解,提高学生的实验参与度,使学生掌握基本的理论知识。将CFD模拟与实验测试技术相结合进行教学,可以极大地提升学生的学习兴趣和求知欲,有效提高教学水平和教学质量。 Experiment of fluid mechanics is a compulsory project in the experiments of resource recycling science and engineering.In the experimental teaching session,the numerical simulation of fluid mechanics is combined with the teaching of experimental testing technology to strengthen student*understanding of theoretical knowledge of fluid mechanics.Taking the visualization experiment of cylindrical orbiting tail vortex field as an example,a CFD simulation App is developed based on COMSOL simulation software.It can support carrying out physical modeling,meshing,variable parameter simulation and other numerical simulation content,and through the pressure cloud map,streamline and other simulation results to analysis the Carmen vortex street shedding frequency,and then enhance students understanding of fluid mechanics theoretical knowledge and related parameters of the physical meaning,change characteristics,etc.The sense of participation is conducive to students to master the basic theoretical knowledge.Combining the CFD simulation with experimental technology,can greatly enhances students'interest and curiosity of learning,and effectively improves the teaching level and teachingquality.
