Influence of nonlinear radiation on natural convection flow of carbon nanotubes suspended in water-based fluid along a vertical wavy surface

摘要

In this study, we have investigated that how thermal efficiency of the base fluid (water) can be enhanced by incorporating single and multi-walled carbon nanotubes in the presence of nonlinear thermal radiation along a vertical wavy surface. The mixture of carbon nanotubes with the base fluid enhances the convection process and this process can speed up by increasing the radiation effects. Due to the enhancement in the convection process of the nanofluid, the fluid particles disperse more rapidly, and consequently the fluid motion also increases. The proposed mathematical model of the natural convection flow of carbon nanotubes suspended in a water-based fluid along a vertical wavy surface under the radiation effect is developed in the form of partial differential equations and then further reduced to a dimensionless nonsimilar system. A numerical procedure is adopted to obtain the result for emerging dimensionless parameters. The outcomes of this study are presented in the form of numerical data and graphs.
