Hodographic study of plane micropolar fluid flows
International Journal of Mathematics and Mathematical Sciences, Volume 18, Issue 2, Page 357-364, 1995., 1995 Equations of steady flow of a plane micropolar fluid are transformed to the hodograph plane by means of the Legendre transform function of the streamfunction. Results are summarized in the form of a theorem, some flow problems are investigated as applications of this theorem and exact solutions and geometry of the flow are obtained in each case.

An Energetic Variational Approach for ion transport
, 2014 The transport and distribution of charged particles are crucial in the study of many physical and biological problems. In this paper, we employ an Energy Variational Approach to derive the coupled Poisson-Nernst-Planck-Navier-Stokes system.

On the unsteady flow of two visco‐elastic fluids between two inclined porous plates
International Journal of Stochastic Analysis, Volume 5, Issue 2, Page 131-138, 1992., 1992 This study is concerned with both hydrodynamic and hydromagnetic unsteady slow flows of two immiscible visco‐elastic fluids of Rivlin‐Ericksen type between two porous parallel nonconducting plates inclined at a certain angle to the horizontal. The exact solutions for the velocity fields, skin frictions, and the interface velocity distributions are ...

A single exponential BKM type estimate for the 3D incompressible ideal MHD equations
Boundary Value Problems, 2014 In this paper, we give a Beale-Kato-Majda type criterion of strong solutions to the incompressible ideal MHD equations. Instead of double exponential estimates, we get a single exponential bound on ∥(u,h)∥Hs (s>52).

Hodographic study of non‐Newtonian MHD aligned steady plane fluid flows
International Journal of Mathematics and Mathematical Sciences, Volume 13, Issue 1, Page 93-113, 1990., 1990 A study is made of non‐Newtonian HHD aligned steady plane fluid flows to find exact solutions for various flow configurations. The equations of motion have been transformed to the hodograph plane. A Legendre‐transform function is used to recast the equations in the hodograph plane in terms of this transform function.

Invariant conservative finite-difference schemes for the one-dimensional shallow water magnetohydrodynamics equations in Lagrangian coordinates [PDF]
Open Communications in Nonlinear Mathematical PhysicsInvariant finite-difference schemes for the one-dimensional shallow water equations in the presence of a magnetic field for various bottom topographies are constructed. Based on the results of the group classification recently carried out by the authors,

Local existence and uniqueness for the non-resistive MHD equations in homogeneous Besov spaces
, 2017 In the paper, we consider the Cauchy problem of the non-resistive MHD equations in homogeneous Besov spaces. We prove the local existence and uniqueness of the solution to the non-resistive MHD equations by using the iterative scheme and compactness ...

Magnetohydrodynamic channel flow and variational principles
International Journal of Mathematics and Mathematical Sciences, Volume 10, Issue 2, Page 391-394, 1987., 1987 This paper deals with magnetohydrodynamic channel flow problems. Attention is given to a variational principle where the boundary conditions are incorporated via a suitable functional which is stationary at the solution of the given problem; the trial functions used for the approximate solution need not satisfy any of the given boundary conditions.

The Relaxation Limits of the Two-Fluid Compressible Euler-Maxwell Equations
Journal of Partial Differential Equations, 2018 In this paper we consider the relaxation limits of the two-fluid Euler-Maxwell systems with initial layer. We construct an asymptotic expansion with initial layer functions and prove the convergence between the exact solutions and the approximate ...
