報告摘要:In this paper, we are concerned with the vanishing viscosity and dynamic microrotation viscosity limit for the 3D incompressible micropolar system in the half space. When the Navier boundary condition for the velocity and non-slip boundary condition for the angular velocity are imposed, we prove that in an interval of time independent of viscosity, the solutions of such system are uniformly bounded in both a conormal Sobolev space and $L^\infty$ space in the inviscid limit. Based on the uniform estimates we show the convergence of the viscous micropolar system to the corresponding inviscid system as the viscosity and dynamic microrotation viscosity tend to zero.
