Abstract:

This paper investigates the inviscid flow field around the 7A multibladed rotor in hover using three mesh strategies of growing complexity: chimera method, automatic mesh generation and automatic mesh adaptation. One major drawback when generating chimera grids is the necessity of manually controlling the overlap between grids and the grid spacing in the interpolation regions. For this reason, an automatic mesh generation procedure has been developed. Its ability to generate overset grids that possess the proper amount of overlap is demonstrated in this paper. Analysis of the chimera results reveals a strong dissipation of the vortical wake. The remainder of the study shows how this can be improved by mesh adaptation.
