| description | A mathematical model for two dimensional unsteady magneto-convective flows with
heat and mass transfer in the presence of a time dependent magnetic field is presented. The system
of partial differential equations governing the transport problem is converted to a system of ordinary
differential equations via two parameter scaling group transformations, before being solved
using an implicit finite difference method. Computed results for non-dimensional velocity, temperature
and concentration distributions as well as skin friction factor, local Nusselt number and Sherwood
number are discussed for various values of the controlling parameters (Prandtl number,
Schmidt number, Richardson number, magnetic field and buoyancy ratio). It is found that the magnetic
field causes an increase in the rate of the heat and mass transfers. The buoyancy ratio increases
the heat transfer rates and decreases the mass transfer rates. |
