In the teaching process of engineering fluid mechanics, it is found that students feel very hard of this course especially hard to grasp the complex theoretical knowledge. Since simulation method as one of two teaching methods (experiment and simulation methods) has been adopted relatively less, improving teaching efficiency may be realized by increasing the application of simulation method. With the gradually enhancement of computer application ability and knowledge expanding of undergraduates, it is proposed by this paper that teaching cases with professional background, comprehensive theory and software application could meet the needs of the development of the current curriculum and students.
