Abstract
The theme of this study is to investigate the impact of radiation with Thompson and Troian boundary slip on CNT-Fe3O4/kerosene oil (KO) hybrid nanofluid flow across a porous exponentially stretching sheet. The viscosity is considered to be temperature-dependent using Reynolds viscosity model. A comparative analysis is done for SWCNT-Fe3O4/KO and MWCNT-Fe3O4/KO. Methodology: The nonlinear partial differential equations (PDEs) are remodeled into non-dimensional ordinary differential equations (ODEs) using suitable similarity transformation. To solve the non-dimensional equations, the Legendre wavelet collocation technique (LWCT) is applied. The code is validated numerically as well as graphically with previous works and found to be in good agreement with them. Findings: It has been observed that thermal profiles are enhanced with the rise in radiation and heat generation. Additionally, in comparison, the velocity profile of MWCNT-Fe3O4/KO is found superior to SWCNT-Fe3O4/KO. It is observed that heat transfer (HT) rate is enhanced by 30.11% on elevating the volume fraction of Fe3O4 from 1% to 10% and is represented by a scatter plot.
