有限元法求解调压室结构中的流固耦合问题
首发时间:2009-07-03
摘要:近年来,国内外越来越多的学者开始用数值方法研究流固耦合问题,人们发现许多工程事故是由于流固耦合作用造成的,表明在某些情况下流固耦合是不容忽视的。本文简单介绍了有限元法和流固耦合的基本原理,并给出了应用有限元法求解水利工程调压室结构中的流固耦合问题的理论基础。随着数值计算方法及计算机技术的发展,对流固耦合的研究将达到更高水平。

Solving The Fluid-solid Coupling Problem in The Surge Tank by Finite Element Method
Abstract:In these year,a growing number of scholars at home and abroad began to study the question of fluid-solid coupling by numerical method. It is found that many projects as a result of the accident was caused by fluid-solid coupling , In some cases show that the fluid-solid coupling can not be ignored. This paper describes the basic principles of finite element method and fluid-solid coupling, also describes the application of FEM in fluid-structure coupling problem in surge tank. With the development of the numerical method and computer technology, the research on fluid-solid coupling will reach a higher level.
Keywords: numerical calculation finite element method fluid-solid coupling surge tank
