碩士 === 國立臺灣大學 === 造船工程學系 === 86 === The main idea of this article is to analyze the incompressible viscous flow field in moving grids. For a flow field which varies with time, we use the moving grid method so that the computational domain can change consistently adapt the physical domain. In the discretization of space and time variables, we use the Galerkin weighted residual method and semidiscrete finite element method, respectively. In this article we solve the test problem which is amenable to exact solution to prove the correctness of the method developed here. Besides, we also discuss the flow which passes through two flexible bending plates to show that the method is applicable to industrial flows.
