HIGH-ORDER SPECTRAL METHODS FOR COMPRESSIBLE FLOWS ON UNSTRUCTURED MESHES

HIGH-ORDER SPECTRAL METHODS FOR COMPRESSIBLE FLOWS ON UNSTRUCTURED MESHES

Breviglieri, C.; Moreira, F. M.; Azevedo, J. L. F.

Full Article:

The present work considers the use of high-order numerical methods for compressible aerodynamic solutions on unstructured meshes. The primary interest of the paper is to investigate the proper solution accuracy and efficiency of the Spectral Finite Volume (SFV) and Spectral Difference (SD) methods. The SFV method can easily be adapted to a finite volume solver while the SD method is designed for a finite difference framework. The mesh element support is also different for these schemes and will most likely affect the solution of a particular problem. The present work compares the order of accuracy and resolution capabilities of the two schemes for literature test cases.
