Abstract
Energy restoration is the prime issue for the researcher and they have tried to develop advanced techniques and resources for renewable energy. The nanofluid is one of the resources for the restoration of energy which depends on the dynamic thermophysical properties of metal nanoparticles. The recent study is concerned with the thin film flow of carbon nanotubes (CNTs) water-based nanofluid for the improvement of heat transfer applications. The flow of two types of CNTs nanofluid was studied, comprising single-walled carbon nanotube (SWCNT) and multi-walled carbon nanotube (MWCNT) over the surface of a thin stirring needle. The study has been carried out in the presence of a magnetic effect and viscous dissipation. The BVP 2.0 package has been used for the solution of the modeled problem. The effect of the physical constraints like Prandtl number, magnetic field and Eckert number vs the momentum and thermal boundary layers has been analyzed. The sum of the residual errors has been obtained up to the 20th order estimates to settle the strong convergence of the problem. The obtained results show that the thin film has a quick response to the increasing of heat transfer rate over the surface of a thin needle as compared to the thick boundary layers.
