On a regularization of the magnetic gas dynamics system of equations
arXiv:1211.3539 · doi:10.3934/krm.2013.6.533
Abstract
A brief derivation of a specific regularization for the magnetic gas dynamic system of equations is given in the case of general equations of gas state (in presence of a body force and a heat source). The entropy balance equation in two forms is also derived for the system. For a constant regularization parameter and under a standard condition on the heat source, we show that the entropy production rate is nonnegative.
