Abstract:
The Boltzmann kinetic equation is considered in a new formulation with nonequilibrium distribution functions on free boundaries, which makes it possible to simulate nonequilibrium superand subsonic flows. Transport processes for such flows are analyzed. The possibility of anomalous transport is determined, in which case the heat flux, temperature gradient, and the corresponding components of the nonequilibrium stress tensor and the velocity gradient have the same sign.
Key words:
rarefied gas, Boltzmann kinetic equation, model kinetic equations, nonequilibrium freeboundary conditions, anomalous transport, numerical method.
