Abstract

In this paper, we consider the inviscid limit of a nonhomogeneous incompressible Navier–Stokes system with a slip-without-friction boundary condition. We study the convergence in strong norms for a solution and obtain the convergence rate in space W 2 , p ( Ω ) when the boundary is flat. We need to establish the uniform bound of the solution in space W 3 , p ( Ω ) , and the key of proofs is to obtain a priori estimation of ∂ t u in space W 1 , p ( Ω ) .
