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.

Pointwise wave behavior of the Navier-Stokes equations in half space [PDF]

open access: yes, 1952
In this paper, we investigate the pointwise behavior of the solution for the compressible Navier-Stokes equations with mixed boundary condition in half space. Our results show that the leading order of Green's function for the linear system in half space

Global Strong solution with vacuum to the 2D nonhomogeneous incompressible MHD system [PDF]

open access: yes, 2012
In this paper, we first prove the unique global strong solution with vacuum to the two dimensional nonhomogeneous incompressible MHD system, as long as the initial data satisfies some compatibility condition.

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

On the complete phase synchronization for the Kuramoto model in the mean-field limit [PDF]

open access: yes, 2014
We study the Kuramoto model for coupled oscillators. For the case of identical natural frequencies, we give a new proof of the complete frequency synchronization for all initial data; extending this result to the continuous version of the model, we ...

Self-Similar Solutions with Elliptic Symmetry for the Compressible Euler and Navier-Stokes Equations in R^{N}

open access: yes, 2011
Based on Makino's solutions with radially symmetry, we extend the corresponding ones with elliptic symmetry for the compressible Euler and Navier-Stokes equations in R^{N} (N\geq2).
