K. Piechor et T. Platkowski, Kinetic and hydrodynamic travelling wave solutions of 2-velocity models ofthe extended Boltzmann equation, TRANSP THEO, 29(6), 2000, pp. 627-659
We find new types of travelling wave solutions which join rest points of ge
neral 2 - velocity models of the extended Boltzmann equation. The new solut
ions exhibit oscillations of the density around a stationary state. For the
first time we derive the hydrodynamic approximations for such models. We s
tudy the travelling wave solutions of these equations as well, and compare
them with the corresponding solutions of the kinetic equations.
