Effect of Jeffery fluid on heat and mass transfer past a vertical porous plate with Soret and variable thermal conductivity

Abstract

This present study examines the effect of Jeffery fluid on heat and mass transfer past a vertical porous plate with Soret and variable thermal conductivity. The equations in dimensionless form have been solved numerically by implicit finite difference schemes of Crank – Nicolson type. Results are shown graphically for the velocity profiles, the temperature profiles, and the concentration profiles with different values of physical parameters like Jeffery parameter, radiation, chemical reaction, thermal Grashof number, solutal Grashof number, Schmidt number, Prandtl number, magnetic parameter, Dufour number, Soret number, permeability parameter, suction parameter, heat generation parameter, and Eckert number. It is observed that the velocity becomes higher as Gr, Gc, Ec, Du, Sr, S, K, γ, and t increased but decreases for Pr, Sc, M, R, and λ1. The temperature profile increases due to the presence of heat generation, Dufour number, and time but reduces for increased values of Prandtl number and suction. Similarly, concentration rises with Soret number and time, and decreases with increasing values of Schmidt number Sc and suction.
