Low Mach number limit on thin domains

Analysis of PDEs 2020-01-29 v2

Abstract

We consider the compressible Navier-Stokes system describing the motion of a viscous fluid confined to a straight layer Ωδ=(0,δ)×R2\Omega_{\delta}=(0,\delta)\times\mathbb{R}^2. We show that the weak solutions in the 3D domain converge strongly to the solution of the 2D incompressible Navier-Stokes equations (Euler equations) when the Mach number ϵ\epsilon tends to zero as well as δ0\delta\rightarrow 0 (and the viscosity goes to zero).
