Exact solution of the Boltzmann equation in the homogeneous color conductivity problem. (English) Zbl 0935.82559

Summary: An exact solution of the Boltzmann equation for a binary mixture of “colored” Maxwell molecules is found. The solution corresponds to a nonequilibrium homogeneous steady state created by a nonconservative external force. Explicit expressions for the moments of the distribution function are obtained. By using information theory, an approximate velocity distribution function is constructed, which is exact in the limits of small and large field strengths. Comparison is made between the exact energy flux and the one obtained from the information theory distribution.
