Response Analysis of Fluid-structure Interaction in Pipelines Transporting Fluids

    摘要
  • 摘要: 采用结构有限元方法和流体CFD方法，研究变化流速下结构和流体的瞬态响应，实现管道与流体间的双向耦合，并得到管道位移、水动压力的时间历程曲线。通过MATLAB频域转换得到了结构和流体的响应频率。

     

    Abstract: the present work,the transient response of structure and fluid in the pipelines with a changing flow velocity are studied by using the finite element method for structure and the CFD method for fluid. On the basis of this study,the hi-directional coupling is achieved,the time history curve of hydrodynamic pressure of fluid and the displacement in pile wall are obtained. And the response frequencies of structure and fluid are calculated by MATLAB through frequency domain conversion.
