直交格子法における埋め込み境界法とCut-Cell法の比較: 壁面近傍での圧力・せん断応力分布の検証

In this paper, an immersed boundary method (IBM) and a cut-cell method on Cartesian grids are compared. In order to understand the characteristics of the two methods, two dimensional steady flow problems are solved. Near-wall pressure and shear stress distributions are investigated in detail. The results show that the cut-cell method is superior to IBM in grid convergence. However, the oscillation of the skin friction coefficient distributions is found in the cut-cell method, whereas IBM gives smooth distributions.
