Hydromagnetic partial slip flow, heat and mass transfer of a viscoelastic third grade fluid embedded in a porous medium
A mathematical model is analyzed to study the hydromagnetic flow, heat and mass transferÂ of a viscoelastic third grade fliud with partial slip past an infinite constant surface temperature
porous plate embedded in a porous medium. The governing partial differential equations are transformedÂ into a set of highly coupled ordinary differential equations, which are solved by using midpointÂ integration scheme along with Richardsonâ€™s extrapolation. The influence of flow parameters
such as slip, magnetic interaction parameter Mn, permeability parameter r, non-Newtonian fluid characteristicsÂ K and other thermophysical parameters on the dimensionless velocity, temperature andÂ concentration profiles are examined carefully and shown graphically. Numerical results including the
development of wall shear stress, local rates of heat as well as mass transfer for pertinent parametersÂ across the boundary layer are investigated and displayed in tabular form. It is revealed that theÂ fluid becomes more shear thickening as the value of the velocity, thermal and concentration boundary
layers decrease; the velocity and thermal boundary layer decrease with an increase in the slip; andÂ the influence of increasing Schmidt number Sc is to accelerate the fluid velocity and decrease theÂ concentration boundary layer thickness of the flow field.
