Abstract
In this paper, the CFD technology and the analysis of a practical engineering example are combined in the teaching of engineering fluid mechanics. Through the numerical simulation of the practical engineering example, the flow field is visualized and the abstract theoretical knowledge becomes more vivid, which is beneficial to the students' understanding and learning. The flow analysis of the engineering example includes many theoretical knowledge points and improves the students' comprehensive ability and innovative thinking. A swirl mixer is taken as an example for numerical simulation and its internal flow field is analyzed. The analysis involves many theoretical points, such as Bernoulli equation, total pressure, static pressure, streamline and vortex etc. So these knowledge points are digested and the understanding is deepened. Therefore, the engineering fluid mechanics teaching with practical engineering examples and CFD technology is a good teaching method, which enhances the traditional teaching mode with multimedia and blackboard and improves the teaching effect compared with previous injection teaching, and is worthy of discussing and trying.
