Abstract

We investigate the asymptotic behavior of solutions to the initial boundary value problem for the micropolar fluid model in a half line $\R_{+}:=(0,\infty).$ Inspired by the relationship between micropolar fluid and Navier-Stokes, we prove that the composite wave onsisting of the transonic boundary layer solution, the 1-rarefaction wave, the viscous 2-contact wave and the 3-rarefaction wave for the inflow problem on the micropolar fluid model is time-asymptotically stable under some smallness conditions. Meanwhile, we obtain the global existence of solutions based on the basic energy method.
