Development Of A Flow Solver Employing Local Adaptation Based On Multiscale Analysis On B-Spline Gri

In the framework of this paper, the basic concepts and preliminary results of a new ow solver, which employs locally h-adaptive grids with hanging nodes, are presented. The new method consists of an integrated framework, including a novel grid generation using B-Splines, advanced adaptation criteria based on multiscale analysis and a ow solver which is capable to operate on arbitrary un-structured meshes. Several test cases for stationary, inviscid ows have been studied to validate the basic method. Firstly, the so called Ringleb ow has been considered to assess the spatial accuracy of the scheme. Secondly, the ow around a wing section has been investigated in subsonic as well as in transonic Mach number regime. The results of the present scheme are in good agreement with experimental data and other ow solvers.
