摘要/Abstract

摘要： A stabilized finite element algorithm potential for wind-structure interaction (WSI) problem is presented in this paper. Streamline upwind Petrov-Galerkin (SUPG) scheme of the large eddy simulation (LES) of dynamic sub-grid scale (DSGS) is developed under the framework of arbitrary Lagrangian-Eulerian (ALE) description to solve the governing equations. High stabilization is achieved by a three-step technique in the temporal discretization. On the other hand, the partitioned procedure is employed for the consideration of the coupled WSI problem. Newmark integral method is introduced for the computation of structure domain, while spring analogy method is used for the grid update of the mesh domain. The developed computational codes are applied to the analysis of wind-induced effect of a spatial latticed structure. The numerical predictions of the three-dimensional wind flow features, the wind pressures and the wind-induced effect of spatial structures are given. Comparisons are made between the effects of rigid structure in view of the WSI.
