Effect of Radiation on Heat and Mass Transfer Magnetohydrodynamic Casson Fluid Flow in a Vertical Channel

Abstract

The present study examines effect of radiation on Magnetohydrodynamic
(MHD) convective boundary layer, flow of a Casson fluid with heat and mass
transfer in a channel. The fluid investigated is electrically conducting. The
governing flow equations are converted into dimensionless form using
appropriate non-dimensional parameters and variables and then numerically
solved by explicit finite difference method (EFDM). Special attention was given
to analyse the effect of thermo physical parameters of engineering interests
associated with the flow quantities viz. velocity, temperature, concentration field
and presented through graphs after series of numerical experiments. It was
found that heat generation has tendency to enhance the fluid velocity as an
opposite result is seen with chemical reaction parameter. Comparison of
present results with the previous literature was carried out to show the accuracy
of the results.
