Rigorous derivation of the asymptotic model describing a nonsteady micropolar fluid flow through a thin pipe
Original language description
In this paper we study a time-dependent flow of an incompressible micropolar fluid through a pipe with arbitrary crosssection. The effective behavior of the flow is found by means of rigorous asymptotic analysis with respect to the small parameter representing the pipe's thickness. The complete asymptotic expansion (up to an arbitrary order) of the solution is constructed with detailed analysis of the boundary layers provided. The convergence of the expansion is proved ustifying the usage of the formally derived asymptotic model.
