This paper presents the analytical results of the incompressible micropolar fluid flowing through a thin cylindrical pipe filled with porous medium, and performs asymptotic analysis in the critical case of strong coupling between velocity and microrotation. The error estimates are also derived to rigorously validate the proposed effective model.
This paper reports the analytical results on the incompressible micropolar fluid flowing through a thin (or long) cylindrical pipe filled with porous medium. We start from the Brinkman-type system governing the filtration of the micropolar flow and perform the asymptotic analysis in the critical case characterized by the strong coupling between the velocity and microrotation. The error estimates are also derived providing the rigorous justification of the proposed effective model.
