Effect of Electromagnetic Field on Forced Convective Heat Transfer in a Vertical Wavy Channel Divided by a Perfectly Conductive Baffle

Abstract

The effect of electromagnetic field on forced convective heat transfer in open-ended vertical wavy channel was studied. The channel was divided into two streams by means of a thin, perfectly conducting baffle and hence the velocity was individual in each passage. The fluid was set with constant initial velocities by a pump. The coupled, nonlinear partial differential equations were solved numerically valid for small values of amplitude and frequency parameter. Numerical results were presented graphically for the distribution of velocity and temperature fields for varying physical parameters such as baffle position, Reynolds number, wall temperature ratio, Hartmann number and electric field load parameter at different positions of the baffle. It was established that, an increase in Reynolds number, leads to increase in velocity. This increase in velocity is further enhanced with increase in channel width. The electric load enhances velocity when it is negative but it retarded when it is positive. The increase in Hartmann number decreases the flow velocity of fluid in a channel. The wall temperature ratio and the Prandtl number enhance temperature distribution at different positions of the partition.
