Abstract:

Several grid generation methods and their numerical simulation of flow field are discussed. A multiblock patched grid for a modern twin vertical tail fighter and a domain decomposition solution of the Euler equation are given. A zonal patched grid for a wing with control surface deflection and Euler solution for the flow around the wing are also given. The overlapping grid method, unstructured grid method and adaptive Caresian grid method are discussed for a two dimensional multielement airfoil.

Key words: zonal patched grid, zonal overlapping grid, unstructured grid, adaptive Cartesian grid, Euler equation
