Abstract:
The problem of steady barotropic motion of a multicomponent medium consisting of viscous compressible fluids in a bounded domain of three-dimensional space is formulated. The viscosity matrices are assumed to be arbitrary (nondiagonal). The solvability of a regularized (approximate) problem is proved.
Keywords:
existence theorem, steady barotropic flow, viscous compressible multifluid, viscosity matrix.
