Global convergence rates from relaxed Euler equations to Navier–Stokes equations with Oldroyd-type constitutive laws

Abstract:In a previous work (Peng and Zhao 2022 J. Math. Fluid Mech.
24 29), it is proved that the 1D full compressible Navier–Stokes equations for a Newtonian fluid can be approximated globally-in-time by a relaxed Euler-type system with Oldroyd’s derivatives and a revised Cattaneo’s constitutive law. These two relaxations turn the whole system into a first-order quasilinear hyperbolic one with partial dissipation. In this paper, we establish the global convergence rates between the smooth solutions … Show more
