Abstract

The zero dissipation limit problem of the Navier–Stokes equations with zero viscosity in the case of the superposition of two rarefaction waves and a contact discontinuity is considered in this paper. It is proved that when the heat conductivity coefficient tends to zero, there exists a unique global solution of the compressible Navier–Stokes equations which converges uniformly to the Riemann solution of the corresponding Euler equations away from the initial time and the contact discontinuity. In addition, the uniform convergence rate in terms of the heat conductivity coefficient is obtained. This result is proved by a combination of the energy method from [F.M. Huang, Y. Wang, and T. Yang, Kinet. Relat. Models, 3:685–728, 2010] and [S.X. Ma, J. Math. Anal. Appl., 387:1033–1043, 2012].
