Inviscid flux-splitting algorithms for real gases with non-equilibrium chemistry

lnviscid Flux-Splitting Algorithms for Real Gases with Non-equilibrium Chemistry

Several flux-splitting methods for the inviscid terms of the compressible-flow equations are derived for gases that are not in chemical equilibrium. Formulas are presented for the extension to chemical nonequilibrium of the Steger-Warming and Van Leer flux-vector splittings, and the Roe flux-difference splitting. The splittings are incorporated in a TVD algorithm and applied to one-dimensional ...

Shock Profiles for Non Equilibrium Radiating Gases

We study a model of radiating gases that describes the interaction of an inviscid gas with photons. We show the existence of smooth traveling waves called ’shock profiles’, when the strength of the shock is small. Moreover, we prove that the regularity of the traveling wave increases when the strength of the shock tends to zero.

Non - equilibrium layered lattice gases *

We have studied several nonquilibnum lattice gases with paniclexonsening dynamics. The lattice consists of two planes, and particles interact (mad) only with nearest-neighbour particles within the same plane but may hop to the other. In addition to the standard heat bath at temperalure T, a mechaoism exists that biases a principal axis, namely. we assume either that particles are also driven by...
