“…Physically, this is true because the increase in the Prandtl number is due to increase in the viscosity of the fluid which makes the fluid thick and hence causes a decrease in the velocity of the fluid. It is observed from Fig.4 that an increase in Grashof number Gr , leads to rise in the values of fluid velocity 1 u for both the stationary wall as well as for the impulsive motion of one of the walls due to enhancement in buoyancy force. Figs.5 and 6 show that the fluid velocity 1 u increases for both the stationary wall as well as for the impulsive motion of one of the walls with an increase in either temperature difference ratio T r or time  .…”

“…This trend is consistent with many classical studies on magneto-convection flow. Fig.3 shows that the fluid velocity 1 u decreases for both the stationary wall as well as for the impulsive motion of one of the walls with an increase in Prandtl number Pr . Physically, this is true because the increase in the Prandtl number is due to increase in the viscosity of the fluid which makes the fluid thick and hence causes a decrease in the velocity of the fluid.…”

“…These flows have been studied by assuming the plates at two different constant temperatures or temperature of the plates varying linearly along the plates etc. Singer (1965) has assessed the unsteady free convection heat transfer with magnetohydrodynamic effects in a channel regime. Joshi (1988) has studied the transient effects in natural convection cooling of vertical parallel plates.…”

The transient MHD natural convection flow of a viscous incompressible electrically conducting fluid confined between vertical walls heated/cooled asymmetrically has been studied. We have considered two different cases (i) when one of the walls is stationary and (ii) when one of the walls starts to move impulsively. The governing equations have been solved analytically using the Laplace transform technique. The velocity field and temperature distribution are being presented graphically. The fluid velocity decreases for both the stationary wall as well as for impulsive motion of one of the walls with an increase in either magnetic parameter or Prandtl number. An increase in fluid temperature occurs due to an increase in temperature difference ratio. Further, the shear stress increases for both the stationary wall as well as for impulsive motion of one of the walls with an increase in either Grashof number or temperature difference ratio or time. The rate of heat transfer at the wall 0   increases with an increase in Prandtl number while it decreases with an increase in temperature difference ratio.

This paper is concerned with the unsteady hydromagnetic boundary-layer flow past a semi-infinite flat plate when the oncoming free stream is perturbed by an arbitrary function of time and the applied magnetic field is parallel to the plate far away from it. Following Lighthill, the two-dimensional boundary-layer equations are separated into those representing steady and unsteady parts of the flow and they have been solved in sequence. For the unsteady part of the motion two types of solutions are obtained, one for large times and the other for small times. Also the quasi-steady solution is obtained in terms of the steady solution. The skin friction and the tangential magnetic field at the plate are calculated.
