计算流体力学线上线下混合式课程改革的探讨

针对新冠疫情的特殊时期需求，以及数字化发展之大趋势，线上线下混合式课程改革与实践受到越来越多的关注。本文主要探讨了计算流体力学（computational fluid dynamics, CFD）的线上线下混合式课程改革与实践方法，提出线下理论教学、线上案例教学、线上线下混合式课堂的改革方法。同时，引入课程思政元素，潜移默化地激发学生爱国热情和民族精神，鼓励学生利用CFD解决卡脖子难题，实现专业知识、工程应用、国家发展的统一。

DISCUSSION ON THE ONLINE AND OFFLINE BLENDED COURSE REFORM OF COMPUTATIONAL FLUID DYNAMICS

In response to the special needs of the COVID-19 epidemic and the general trend of digital development, the reform and practice of online and offline blended courses have received more and more attention. This paper mainly discussed the online and offline blended course reform and practice methods of computational fluid dynamics (CFD), and puts forward the reform methods of offline theory teaching, online case teaching, and online and offline blended teaching. At the same time, the ideological and political elements of the course are introduced to imperceptibly stimulate students' patriotic enthusiasm and national spirit, encourage students to use computational fluid dynamics to solve bottleneck problem, and realize the unity of professional knowledge, engineering application, and national development.
