Abstract:

An initial boundary value problem for one-dimensional equations of the dynamics of compressible viscous multicomponent media in the isothermal case is considered. A theorem of the existence and uniqueness of a strong solution to the problem is proved without restrictions on the structure of the viscosity matrix, except for the standard requirements of symmetry and positive certainty.

Keywords: existence and uniqueness theorem, unsteady initial boundary value problem, compressible viscous  fluid, multicomponent flow.
