|
| |
|
Resumo :
|
|
IN THIS PAPER, A STABLE PETROV-GALERKIN FORMULATION FOR
THE COMPRESSIBLE EULER EQUATIONS IS COMBINED WITH A P
-ADAPTIVE REMESHING REFINEMENT. THE STABILITY ENGENDERED BY THIS FORMULATION
ALLOWS USING THE SAME SPATIAL INTERPOLATION ORDER IN ALL THE VARIABLES EVEN
IN THE PRESENCE OF STEEP GRADIENTS. THE RESULT IS AN ACCURATE AND EFFICIENT
SCHEME APPROPRIATED TO SOLVE PROBLEMS PRESENTING SHOCKS AND BOUNDARY-LAYERS.
KEY-WORDS: P ENRICHMENT, PETROV-GALERKIN, COMPRESSIBLE FOWS |
