Energy equality in the isentropic compressible Navier-Stokes-Maxwell equations

Electronic Research Archive, 2023
This paper concerns energy conservation for weak solutions of compressible Navier-Stokes-Maxwell equations. For the energy equality to hold, we provide sufficient conditions on the regularity of weak solutions, even for solutions that may include exist ...

Analytical Solution to 1D Compressible Navier-Stokes Equations

Journal of Function Spaces, 2021
There exist complex behavior of the solution to the 1D compressible Navier-Stokes equations in half space. We find an interesting phenomenon on the solution to 1D compressible isentropic Navier-Stokes equations with constant viscosity coefficient on x,t ...

Revisiting the Reynolds-averaged Navier–Stokes equations

Open Physics, 2022
This study revisits the Reynolds-averaged Navier–Stokes (RANS) equations and finds that the existing literature is erroneous regarding the primary unknowns and the number of independent unknowns in the RANS. The literature claims that the Reynolds stress

The pullback attractor for the 2D g-Navier-Stokes equation with nonlinear damping and time delay

AIMS Mathematics, 2023
In this article, the global well-posedness of weak solutions for 2D non-autonomous g-Navier-Stokes equations on some bounded domains were investigated by the Faedo-Galerkin method.

A Liouville theorem for the planer Navier-Stokes equations with the no-slip boundary condition and its application to a geometric regularity criterion [PDF]

, 2013
We establish a Liouville type result for a backward global solution to the Navier-Stokes equations in the half plane with the no-slip boundary condition. No assumptions on spatial decay for the vorticity nor the velocity field are imposed.

Generalized Navier–Stokes equations and soft hairy horizons in fluid/gravity correspondence

Nuclear Physics B, 2021
The fluid/gravity correspondence establishes how gravitational dynamics, as dictated by Einstein's field equations, are related to the fluid dynamics, governed by the relativistic Navier–Stokes equations.

Global existence of strong solutions to compressible Navier-Stokes-Korteweg equations with external potential force

AIMS Mathematics, 2023
In this article, we consider a three dimensional compressible Navier-Stokes-Korteweg equations with the effect of external potential force. Under the smallness assumptions on both the external potential force and the initial perturbation of the ...
