چکیده

The paper presents a mathematical analysis of the stability of generalized hydromagnetic thermal shear flows in the Presence of horizontal magnetic field. The physical configuration is that of a horizontal layer of an incompressible inviscid heat conducting fluid of zero electrical resistivity in which there is a differential streaming in the horizontal direction and density variation in the vertical direction while the entire system is confined between two horizontal boundaries of different but uniform temperatures with the temperature of the lower boundary greater than that of the upper one in the presence of a uniform horizontal magnetic field. Results concerning the validity of the principle of exchange of stabilities, existence of non-oscillatory modes and the bounds for the phase velocity of disturbances, etc. are mathematically established for certain classes of differential streaming function. Keywords— Parallel shear flows, Stratification , thermal stability ,instability exchange, Sreaming function

Effect of slip and variable thermal boundary conditions on hydromagnetic mixed convection flow and heat transfer from a non-linearly stretching ‎surface

The effect of partial slip and temperature dependent fluid properties on the MHD mixed convection flow from a heated, non-linearly stretching surface in the presence of radiation and non-uniform internal heat generation/absorption is investigated. The velocity of the stretching surface was assumed to vary according to power-law form. Thermal transport is analyzed for two types of non-isothermal...

Thermal Convection in a (Kuvshiniski-type) Viscoelastic Rotating Fluid in the Presence of Magnetic Field through Porous Medium (TECHNICAL NOTE)

  The effect of magnetic field on an incompressible (Kuvshiniski-Type) viscoelastic rotating fluid heated from below in porous medium is considered. For the case of stationary convection, magnetic field and medium permeability have both stabilizing and destabilizing effect on the thermal convection under some conditions whereas rotation has a stabilizing effect on the thermal convection. In the...
