چکیده
We prove nonlinear stability of viscous shock wave of arbitrary amplitudes to a one-dimensional compressible isentropic Navier-Stokes equations with density dependent viscosity. Under the assumption that the viscous coefficient is given as a power function of density, any viscous shock wave is shown to be nonlinear stable for small initial perturbations with integral zero. In contrast to previous related results [20, 22], there is no restrictions on the power index of the viscous coefficient and the amplitudes of the viscous shock wave in our result.

Stability of Boundary Layers for the Nonisentropic Compressible Circularly Symmetric 2D Flow
In this paper, we study the asymptotic behavior of the circularly symmetric solution to the initial boundary value problem of the compressible non-isentropic Navier-Stokes equations in a two-dimensional exterior domain with impermeable boundary condition when the viscosities and the heat conduction coefficient tend to zero. By multi-scale analysis, we obtain that away from the boundary the comp...
متن کاملStability of Viscous Shocks in Isentropic Gas Dynamics
In this paper, we examine the stability problem for viscous shock solutions of the isentropic compressible Navier–Stokes equations, or p-system with real viscosity. We first revisit the work of Matsumura and Nishihara, extending the known parameter regime for which small-amplitude viscous shocks are provably spectrally stable by an optimized version of their original argument. Next, using a nov...

High frequency perturbations u of a weak planar two dimensional isentropic slightly viscous shock are shown to give a geometric optics expansion u = e if== (u 0 + u 1), where the gradients of the phase functions rf solve eikonal equations related to Rie-mann problems for classical and over-compressive shocks. The main result is a rigorous expansion of the linearized equations describing in deta...

By a combination of asymptotic ODE estimates and numerical Evans function calculations, we establish stability of viscous shock solutions of the isentropic compressible Navier–Stokes equations with γ -law pressure (i) in the limit as Mach number M goes to infinity, for any γ ≥ 1 (proved analytically), and (ii) for M ≥ 2, 500, γ ∈ [1, 2.5] or M ≥ 13, 000, γ ∈ [2.5, 3] (demonstrated numerically)....
متن کاملSelf-propelled motion in a viscous compressible fluid – unbounded domains
In this paper we study the self-propelled motion of a single deformable body in a viscous compressible fluid which occupies whole 3-dimensional Euclidean space. The considered governing system for the fluid is the isentropic compressible Navier-Stokes equations. The main result of this paper is the existence of a weak solution on a time interval (0,+∞).
