Abstract

We consider the compressible Navier–Stokes system describing the motion of a viscous fluid confined to a straight layer . 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 tends to zero as well as (and the viscosity goes to zero).
