*3.3. Concentration*

The impacts of *Sc*, *Nb*, *Nt* and γ on φ(η) are presented in Figures 11–14. Figure 11 shows the profile of φ(η) for dissimilar values of *Sc*. We observe that φ(η) increases with the higher values of *Sc*. The impact of *Nb* and *Nt* on the concentration profile is shown in Figures 12 and 13. Figure 12 shows that the concentration profile reduced as the values of *Nb* reduces. Enhancing thermophoresis process boosts the traveling of particles from higher to lower temperature deference, which results in maximizing the concentration of nanoparticles in the flow regime. Figure 13 show the influence of *Nt* on the concentration profile. The higher values of *Nt* corresponds increasing trends in concentration profile and related momentum boundary layer. Figure 14 shows that φ(η) increases with the higher values of γ in quite the same manner.
