Title: Relaxation-based approximate Riemann solvers for compressible flows


Abstract:
I will present new numerical methods for the Euler equations and the 
ideal MHD (magnetohydrodynamics) equations. These methods satisfy two 
important stability criteria: They preserve positivity of density and 
pressure, and satisfy a discrete entropy inequality. The talk will focus 
on (i) A numerical study for compressible high Mach number flows, 
including isotropic turbulence, and (ii) The extension of the approach 
to MHD. The results are from joint work with Francois Bouchut, Christian 
Klingenberg and
Wolfram Schmidt.
