*3.2. Temperature*

The variations of *Nb* (Brownian motion parameter), *Nt* (thermophoresis parameter), Pr (Prandtl number), and γ (curvature parameter) on temperature profile θ(η) are respectively shown in Figures 7–10. We have shown the effect that is produced by the variation of Brownian motion *Nb* on θ(η) in Figure 7. Brownian motion is the arbitrary movement of small colloidal particles suspended in a fluid, brought about by the collision of the fluid atoms with the particles. An expansion in the Brownian motion impact yields noteworthy movement of nanoparticles, which offers ascend to the fluid kinetic energy and henceforth temperature increments. It is seen that, at fixed *Nb*, initially the profile drops to the lowest value at around η = 0.4, and then rises and reaches to maximum at the largest value of η. By changing *Nb* to larger values, there is an upshift in the temperature function from about η = 0.4 to η = 3.0. This shows that there is an enhancement in the average kinetic energy of the hybrid nanofluid with the higher values of *Nb*. The influence of the thermophoresis parameter (*Nt*) on θ(η) is displayed in Figure 8. It is initiated that rise in *Nt* leads to augmenting both the liquid temperature. The augmented value of *Nt* Shows stouter thermophoretic force due to temperature gradient, which transfers the nanoparticles from the warm surface to the quiescent fluid. Thermophoresis force is generated by temperature gradient, which fashions a degenerate flow away from the surface. Figure 9 depicts the effects that are produced by the variation of the Prandtl number (Pr) over the temperature function θ(η). Figure 9 is portraying the declining behavior of temperature curves for growing values of Prantl number (Pr), since the thickness of the thermal boundary layer reduced by enhancing (Pr). Figure 10 illustrates the variation of θ(η) with respect to the changing values of the curvature parameter γ. It is apparent that θ(η) increases with increasing values of γ.
