*4.5. Nusselt Number*

The effects of variation of thermophoresis parameter on Nusselt number (*Nux*Re−1/2 *<sup>x</sup>* ) is shown in Figure 14. Figure 14 shows the plots for the Nusselt number by varying of thermophoresis parameter against Brownian motion parameter.

One may witness that:

• *Nux*Re−1/2 *<sup>x</sup>* shows a falling pattern with the increase in thermophoresis parameter against Brownian motion parameter.
