effects of Prandtl number Pr on the temperature field. It is observed that an increase in the Prandtl number leads to decrease in the fluid temperature. It is due to the fact that thermal conductivity of the fluid decreases with increasing Pr, resulting a decrease in thermal boundary layer thickness.
The concentration profiles for different values of Schmidt number (Sc) and time t are presented in Figure 11. From this figure it is seen that the concentration decreases with increase in Sc while it increases with time t. Figure 12 reveals the rate of heat transfer coefficient in terms of Nusselt number for different values of radiation parameter R, Prandtl number Pr and Dufour number Dr respectively. It is observed that Nusselt number increases with increasing values of R or Pr but decreases as Du increases. Finally, from Figure 13 it is seen that Sherwood number increases with increase of Sc.
