摘要
流固耦合(Fluid-Structure Interaction,FSI)是目前很多领域研究的热点和难点之一.与国外相比,国内在该方面的研究相对滞后或片面.本文对FSI研究现状和意义、传统风工程理论和方法、流体力学基本理论、流体力学有限元、FSI理论和分析方法等内容作了介绍,探讨了耦合界面条件、边界追踪、网格更新以及大型非线性方程求解等问题,特别对强耦合和弱耦合算法作了理论上的探讨和区分.本文可为流固耦合理论数值模拟提供理论和方法的指导.
The computation of fluid-structure interaction(FSI) is among the most hot and difficult problems in many fields.Compared with other advanced countries,the study on FSI problems in home is lagging and short.The paper is concerned with the computational theory for FSI.The framework includes several aspects: the study progresses in FSI,the theory and method of traditional wind engineering,the basic theory of Fluid Mechanics,the FEM used in Computational Fluid Dynamics(CFD),the theroy and method of FSI computat...
