内容記述 | In order to accurately solve the unsteady fluid motion by large eddy simulation, we have to use a grid-resolution as uniform as possible for the whole flow field. It is often the case that the grid-resolution is deteriorated far from the wall when the structured grid system such as an O-type is employed. There have been many researches on the Adaptive Mesh Refinement (AMR) since 1980s. Note, however, that we should take advantage of the knowledge acquired in the structured grids in the AMR code. Then, we employ the Blocked Adaptive Mesh Refinement (BAMR) to remain the grid-resolution to be preferably unchanged in the computational domain. In this study, we develop an algorithm to generate the blocks with the finer mesh automatically, and apply the BAMR code to the viscous flow analyses around a two-dimensional cylinder, the NACA0012 airfoil configuration, and a three-dimensional cylinder. These test cases show feasible resolutions with the limited CPU resources. | |||||
