Abstract:
The effect of temperature dependent viscosity on magneto hydrodynamic flow of a
viscous incompressible fluid past a continuous moving surface has been studied. A steady, two dimensional laminar flow past a continuous moving surface with uniform surface temperature Tw and velocity Uw moving axially through an electrically conducting fluid has been considered. The x-axis runs along the continuous surface in the direction of the motion and the y-axis is perpendicular to it. The magnetic field is applied along the y-axis. The governing boundary layer equations have been transformed into non dimensional form using a set of dimensionless variables. The resulting non-linear system of partial differential equations governing the flow have been solved numerically by employing the finite difference method. The equations have been solved using Matlab software. The effect of varying various parameters on the velocity and temperature profiles has been obtained. This has been followed by graphical representation of the results. The observations have been discussed. A change in various parameters have been observed to increase, decrease or have no effect on skin friction coefficient, the rate of heat transfer, velocity and temperature profile on a continuous moving surface. It was observed that when magnetic parameter was increased there was a decrease in velocity. Temperature also decreased with increase of magnetic parameter.
