Numerically analyzing more efficiently high-lift aerodynamics of wing/body model with omni-tree Cartesian grids

A modified Cartesian grid method is introduced to simulate the flow fields around wing/body high-lift configurations by using a multi-zone technique. With a face-to-face algorithm, the Euler equations are solved numerically, in combination with the cell-center finite volume method and dual-time stepping scheme. The multi-zone technique is employed to simplify the great difficulties in grid generation. The face-to-face algorithm is constructed to precisely establish the information exchange of flow fields on the interface between zones. The numerical results are presented and compared with experimental data. (C) 2010 Elsevier Masson SAS. All rights reserved.
