The continuity equation and the Euler equation are the core contents of the momentum transfer. The derivation process has always been the focus and difficulty in teaching and students generally reflect it is difficult to understand in the past. In order to make students better understand and master the derivation process of the continuity equation and Euler equation, in the paper, it is discussed the topic teaching method and deduced the continuity equation and Euler equation of fluid flow, and some understanding and experience in topic teaching method for derivation of the continuity equation and Euler equation are shared, providing the reference for teaching of momentum transfer theory.

连续性方程和欧拉方程是动量传输的核心内容,其推导过程一直是教学中的重点和难点,以往教学中学生普遍反映难于理解。为了使学生更好的理解和掌握连续性方程及欧拉方程的推导过程,文章对此专题性教学方法进行探讨,采用易于学生理解和掌握的方法分别推导了流体流动的连续性方程及欧拉方程,并分享了连续性方程和欧拉方程推导专题教学中的一些认识与体会,为动量传输理论的教学提供一定的参考。

The continuity equation and the Euler equation are the core contents of the momentum transfer. The derivation process has always been the focus and difficulty in teaching and students generally reflect it is difficult to understand in the past. In order to make students better understand and master the derivation process of the continuity equation and Euler equation, in the paper, it is discussed the topic teaching method and deduced the continuity equation and Euler equation of fluid flow, and some understanding and experience in topic teaching method for derivation of the continuity equation and Euler equation are shared, providing the reference for teaching of momentum transfer theory.
