This paper presents a finite element formulation for solving multidimension
al compressible flows. This method is inspired by our experience with the S
UPG, finite volume (FV) and discontinuous-Galerkin (DG) methods. Our object
ive is to obtain a stable and accurate finite element formulation for multi
-dimensional hyperbolic-parabolic problems with particular emphasis on comp
ressible flows. In the proposed formulation, the upwinding effect is introd
uced by considering the flow characteristics along the normal vectors to th
e element interfaces. This method is applied for solving inviscid, laminar
and turbulent flows. The one-equation turbulence closure model of Spalart-A
llmaras (S-A) is used. Several numerical tests are carried out, and a selec
tion of two- and three-dimensional experiments is presented. The results ar
e encouraging, and it is expected that more numerical experiments and theor
etical analysis will lead to a greater insight into this formulation. We al
so discuss algorithmic and parallel implementation issues. (C) 2001 Elsevie
