The use of flux-splitting techniques on the Euler equations is considered for high
Mach number, high temperature flows in which the fluid is assumed to be
inviscid air in equilibrium. Three different versions of real gas extensions to the
Steger—Warming and Van Leer flux-vector splitting, and four different versions
of real gas extensions to the Roe flux-difference splitting, are compared with regard
to general applicability and ease of implementation in existing perfect gas g
algorithms. Test computations are performed for the M = 5, high temperature
flow over a 10-degree wedge and the M = 24.5 flow over a blunt body. Although
there were minor differences between the computed results for the three types of
flux-splitting algorithms considered, little variation is observed between different
versions of the same algorithm.
