Some geometric properties of magneto‐fluid flows

International Journal of Mathematics and Mathematical Sciences, Volume 5, Issue 2, Page 385-392, 1982., 1982
By employing an anholonomic description of the governing equations, certain geometric results are obtained for a class of non‐dissipative magnetofluid flows. The stream lines are geodesics on a normal congruence of the surfaces which are the Maxwellian surfaces.

Shear flow past a flat plate in hydromagnetics

International Journal of Mathematics and Mathematical Sciences, Volume 3, Issue 3, Page 521-534, 1980., 1979
The problem of simple shear flow past a flat plate has been extended to the hydromagnetic case in which a viscous, electrically conducting, incompressible fluid flows past an electrically insulated flat plate with a magnetic field parallel to the plate. For simplicity all physical parameters are assumed constant.

Initial boundary value problem and exponential stability for the planar magnetohydrodynamics equations with temperature-dependent viscosity

Advances in Nonlinear Analysis
In this study, we consider the initial boundary value problem of the planar magnetohydrodynamics (MHD) system when the viscous coefficients and heat conductivity depend on the temperature, which are assumed to be proportional to θα{\theta }^{\alpha }, α ...

HEAT AND HALL EFFECT OF AN OSCILLATING PLATE IN A POROUS MEDIUM

, 2020
An exact solution of the flow of heat and viscous fluid on a porous plate by using perturbation is obtained for the conjugate problem of an electrically conducting fluid in the presence of strong magnetic field by introducing the Hall currents. The fluid

Low Mach number and non-resistive limit of magnetohydrodynamic equations with large temperature variations in general bounded domains

Advances in Nonlinear Analysis
This article verifies the low Mach number and non-resistive limit of local strong solutions to non-isentropic compressible magnetohydrodynamic (MHD) equations in general three-dimensional bounded domains when the temperature variation is large but finite.

Wavelet estimate of time series

, 2001
In this paper a wavelet technique to study time series by discrete wavelet coefficients, is proposed. Since time series are mainly represented by histograms we will use the Haar waveletes and the Haar wavelet interpolation [1,2].

RELAXATION OF THE KINEMATIC DYNAMO EQUATIONS

We compute the exact relaxation and Λ-convex hull of the kinematic dynamo equations and show that they coincide. We also find the relaxation in the stationary case and present applications to the infinite-time limit in the kinematic dynamo problem.Peer ...
