Abstract
The variational approach of the steady Euler equations presented at the loth ICNMFD [1] is extended to the treatment of supersonic and hypersonic flows by introducing the energy equation inthe least-squares formulation. The approximation is made with cubic or prismatic linear finite elements and the results are presented for flows around a rectangular flat plate or a thin delta wing for various Mach numbers and angles of attack. They show the occurrence of vortical flows on the upper surface of the wings due to the sharp edges.
