• EFFECTS OF VARIABLE THERMAL CONDUCTIVITY ON HEAT AND MASS TRANSFER WITH JEFFERY FLUID

Abstract

The effects of variable thermal conductivity on heat and mass transfer with Jeffery fluid has been investigated in this paper. The equations have been solved numerically by implicit finite difference schemes of Crank – Nicolson type. Results are shown graphically for the velocity profile, the temperature profile, and the concentration profile with different values of physical parameters like Jeffery parameter, thermal Grashof number, mass Grashof number, Schmidt number, Prandtl number, magnetic parameter, chemical reaction parameter, permeability parameter, suction parameter, heat generation parameter, and Eckert number. It is observed that the velocity becomes higher as Gr, Gc, Ec, S, K,, and t increased but decreases for Pr, Sc, M, R, and . The temperature profile increases due to the presence of heat generation, and time but reduces for increased values of Prandtl number and suction. Similarly, concentration rises with time, and decreases with increasing values of Schmidt number Sc, radiation and suction.
