3-D flow of a compressible viscous micropolar fluid with cylindrical symmetry: uniqueness of a generalized solution
In this paper we consider a nonstationary 3-D flow of a compressible viscous and heat- conducting micropolar fluid, which is in the thermodynamical sense perfect and polytropic. The fluid domain is a subset of R3 bounded with two coaxial cylinders that present solid thermoinsulated walls. The mathematical model is set up in Lagrangian description. If we assume that the initial mass density, temperature, as well as the velocity and microrotation vectors are smooth enough cylindrically symmetric functions, then our problem has a generalized cylindrically symmetric solution for a sufficiently small time interval. Here we prove the uniqueness of this solution.
