Global existence of the two-dimensional axisymmetric Euler equations for the Chaplygin gas with large angular velocities

open access: yesAdvanced Nonlinear Studies, 2022
The Chaplygin gas model is both interesting and important in the theory of gas dynamics and conservation laws, all the characteristic families of which are linearly degenerate. Majda conjectured that the shock formation never happens for smooth data.

Asymptotic study of Leray solution of 3D-Navier-Stokes equations with exponential damping

open access: yesDemonstratio Mathematica, 2023
We study the uniqueness, the continuity in L2{L}^{2}, and the large time decay for the Leray solutions of the 3D incompressible Navier-Stokes equations with the nonlinear exponential damping term a(eb∣u∣2−1)ua\left({e}^{b| u{| }^{{\bf{2}}}}-1)u, (a,b>0a ...

On non-resistive limit of 1D MHD equations with no vacuum at infinity

open access: yesAdvances in Nonlinear Analysis, 2021
In this paper, the Cauchy problem for the one-dimensional compressible isentropic magnetohydrodynamic (MHD) equations with no vacuum at infinity is considered, but the initial vacuum can be permitted inside the region. By deriving a priori ν (resistivity

Global weak solution of 3D-NSE with exponential damping

open access: yesOpen Mathematics, 2022
In this paper, we prove the global existence of incompressible Navier-Stokes equations with damping α(eβ∣u∣2−1)u\alpha \left({e}^{\beta | u{| }^{2}}-1)u, where we use the Friedrich method and some new tools.

The well-posedness of solution to a compressible non-Newtonian fluid with self-gravitational potential

open access: yesOpen Mathematics, 2018
We study the initial boundary value problem of a compressible non-Newtonian fluid. The system describes the motion of the compressible viscous isentropic gas flow driven by the non-Newtonian self-gravitational force. The existence of strong solutions are

Global existence of a radiative Euler system coupled to an electromagnetic field

open access: yesAdvances in Nonlinear Analysis, 2018
We study the Cauchy problem for a system of equations corresponding to a singular limit of radiative hydrodynamics, namely, the 3D radiative compressible Euler system coupled to an electromagnetic field.

On self-similar solutions to degenerate compressible Navier-Stokes equations [PDF]

open access: yes, 2019
We study cavitating self-similar solutions to compressible Navier-Stokes equations with degenerate density-dependent viscosity. We prove both existence of expanders and non-existence of small shrinkers.

Time decay estimates of solutions to a two-phase flow model in the whole space

open access: yesAdvances in Nonlinear Analysis
In this article, we aim to establish the optimal time decay rates of strong solutions to a two-phase flow model derived from a type of coupled fluid-kinetic equation.
