Abstract: Fluid mechanics is a core course for mechanics majors and also a key construction course in the mechanics "101 Plan". The fluid mechanics course team, following the guiding principle of the "101 Plan" of cultivating outstanding mechanics talents who can deeply understand principles, seek truth, utilize data and intelligence, and be innovative, has carried out the construction of the fluid mechanics course, including the construction of knowledge diagrams, course design, textbook revision, and the development of electronic teaching materials. This article mainly introduces the course design of fluid mechanics. Additionally, based on the teaching practices at Zhejiang University and University of Science and Technology of China, it presents reflections on fluid mechanics teaching in the era of digital intelligence. Although digital empowerment can enhance students' learning efficiency, teaching methods that foster students’ understanding of principles and learning initiative are even more important.
