Perturbation Solutions For Magnetohydrodynamics (Mhd) Flow of in a Non-Newtonian Fluid Between Concentric Cylinders

International Journal of Applied Mechanics and Engineering, 2019
The steady-state magnetohydrodynamics (MHD) flow of a third-grade fluid with a variable viscosity parameter between concentric cylinders (annular pipe) with heat transfer is examined.

Resistive and viscous dynamics of finite-amplitude shear waves at a magnetic X-point [PDF]

, 2005
The dynamics and dissipation of axial shear waves, superposed on a planar magnetic X-point in a resistive viscous incompressible plasma, are analyzed numerically and analytically. The interplay of viscous and resistive effects is demonstrated by deriving

Analytical Solutions to the Navier-Stokes-Poisson Equations with Density-dependent Viscosity and with Pressure

, 2010
We study some particular solutions to the Navier-Stokes-Poisson equations with density-dependent viscosity and with pressure, in radial symmetry. With extension of the previous known blowup solutions for the Euler-Poisson equations / pressureless Navier ...

Existence of Viscosity Solutions for Weakly Coupled Cooperative Parabolic Systems with Fully Nonlinear Principle Part

Mathematics
In this paper, the existence of viscosity solutions for weakly coupled, degenerate, and cooperative parabolic systems is studied in a bounded domain. In particular, we consider the viscosity solutions of parabolic systems with fully nonlinear degenerated

Upper- and lower-bound solutions for sectional penetration grouting pressure under time-dependent viscosity of slurry

Yantu gongcheng xuebao, 2023
Under the time-dependent viscosity of slurry, the grouting pressure (p) and the grouting rate (q) are both time-dependent, which makes design and calculation more difficult in grouting project. Firstly, the engineering definitions of grouting pressure (P)

Nonlinear elliptic-parabolic problems

, 2012
We introduce a notion of viscosity solutions for a general class of elliptic-parabolic phase transition problems. These include the Richards equation, which is a classical model in filtration theory.

Vanishing viscosity limit of navier-stokes equations in gevrey class

, 2017
In this paper we consider the inviscid limit for the periodic solutions to Navier-Stokes equation in the framework of Gevrey class. It is shown that the lifespan for the solutions to Navier-Stokes equation is independent of viscosity, and that the ...
