Under assumptions on smoothness of the initial velocity and the external body force, we prove that there exists T-0 > 0, nu* > 0 and a unique family of strong solutions u(nu) of the Euler or Navier-Stokes initial-boundary value problem on the time interval ( 0, T-0), depending continuously on the viscosity coefficient nu for 0 <= nu < nu*. The solutions of the Navier-Stokes problem satisfy a Navier-type boundary condition. We give the information on the rate of convergence of the solutions of the Navier-Stokes problem to the solution of the Euler problem for nu -> 0+.
