中文摘要：
目前对于流体力学基本理论的研究已非常成熟,但从流固耦合问题出发,重新梳理流体力学的基本理论是十分必要的.除了给出传统的Lagrange和Euler描述外,本文针对流固耦合中广泛应用的ALE描述,也给出了ALE描述下流体遵循的基本定律表达式,并根据实际应用,对流体力学基本方程进行简化,从而得到不同的控制方程.
英文摘要：
Although the study on the basic theories of the fluid mechanics is very mature at present,it is necessary to reconstitute the main theories of the fluid mechanics in consideration of FSI(Fluid and Solid Interaction).In addition to introduce the Lagrange and Euler description,the main laws of the fluid mechanics in ALE description used widely in FSI are introduced as well.The governing equations of the fluid mechanics are reduced to different forms taking account to the practical applications.
