>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.
