基于单元变形的网格间流场信息传递方法
New method for transferring flow information among meshes based on mesh deformation
摘要
Abstract
According to the data interpolation problems between the old and new grid in the mesh reconstruction,a flow field information transmission algorithm based on the lattice format supported finite volume method was proposed.In order to realize information transfer between the two sets of the grid,the old cells were moved to the new grid cells by using the unstructured dynamic grid technology and the control equation was solved in time domain,then the datum was assigned to the new grid cells.Result shows that the interpolation error is not introduced in the process of information transmission,the theory precision of the method is equal to the precision of information transmission,and the verification results show that the proposed method is significantly better than that of the second order interpolation method.关键词
