Existence of Weak Solutions to the Problem on Three-Dimensional Steady Heat-Conductive Motions of Compressible Viscous Multicomponent Mixtures

We consider the equations describing the three-dimensional steady heat-conductive motions of compressible viscous multicomponent mixtures. We also prove the existence of weak solutions to the boundary value problem in a bounded domain without any simplifying assumptions on the structure of the viscosity matrix except for the standard physical requirement of positive definiteness.
