Application of CNTs – Al2O3/H2O on a Hybrid Nanofluid in Two-Dimensional Unsteady Flow in a Stretching Sheet: Darcy-Forchheimer Model

Abstract

The fame of carbon nanotube nanoparticles for improving the thermophysical characteristics of fluid molecules has grown recently (Nanoparticles of Carbon nanotubes have attained the fame to enhance the thermophysical properties of fluid molecules). The main objective of this article is to investigate the boundary layer flow of a hybrid nanofluid composed of multi-wall carbon nanotubes (MWCNTs) and single-wall carbon nanotubes (SWCNTs) in combination with alumina and water through a stretching sheet while considering the effects of the magnetic field, thermal radiation, heat dissipation, and slip conditions. Additionally, comparisons and studies of the effects of MWCNTs and SWCNTs nanoparticles on the boundary layer are conducted. The dimensionless similarity transformation is used by the bvp4c algorithm in the MATLAB solver to calculate the numerical solutions of the dimensionless ordinary differential equations. Graphs and tables are used to show the associated model’s physical parameters. In addition, the hybrid nanofluid’s flow pattern is generally slowed down by the magnetic, porosity, and inertia coefficient factors. The rate of heat transfer was boosted by using a larger volume fraction of MWCNTs and SWCNTs.
