LES for wind load estimation by unstructured grid system
ABSTRACT: Recent development of high-performance computers and techniques on computational fluid engineering has enabled us to simulate the complicated flow such as the wind in urban area. Large Eddy Simulation (LES) is expected to be adopted as an effective technique to evaluate wind load on buildings for wind-resistant design. In this research, the accuracy of LES to evaluate surface pressure...
متن کاملCommutative filters for LES on unstructured meshes
Application of large eddy simulation (LES) to flows with increasingly complex geometry necessitates the extension of LES to unstructured meshes. A desirable feature for LES on unstructured meshes is that the filtering operation used to remove small scale motions from the flow commutes with the differentiation operator. If this commutation requirement is satisfied, the LES equations have the sam...
متن کاملAdaptive Solution of Steady Two Dimensional Flow on an Unstructured Grid
Two-dimensional Euler equations have been solved on an unstructured grid. An upwind finite volume scheme, based on Roe's flux difference splitting method, is used to discretize the equations. Using advancing front method, an initial Delaunay triangulation has been made. The adaptation procedure involves mesh enrichment coarsening in regions of flow with high low gradients of flow properties, ac...
