AbstractThis study is devoted to investigate the effect of magnetic field on a reactive unsteady generalized Couette flow with temperature dependent viscosity and thermal conductivity. It is assumed that conducting incompressible fluid is subjected to an exothermic reaction under Arrhenius kinetics, neglecting the consumption of the material. The model nonlinear differential equations governing the transient momentum and energy balance are obtained and tackled numerically using a semi-discretization finite difference technique coupled with Runge-Kutta Fehlberg integration scheme. Important properties of the velocity and temperature fields including thermal stability conditions are presented graphically and discussed quantitatively.

This paper studied Magneto hydrodynamics viscious, incompressible fluid bounded by the parallel non-conducting porous walls. The viscousity of the fluid is assumed to be temperature dependent. The fluid is subjected to a constant pressure gradient and an external uniformmagnetic field perpendicular to the walls. The two walls are kept different but constant temperature while the Joule and viscious dissipation are included in the energy equation. Graphs were presented to show the effects of temperature depentent viscosity on both the velocity and temperature distribution.
