Effect of Thompson and Troian slip on CNT-Fe3O4/kerosene oil hybrid nanofluid flow over an exponential stretching sheet with Reynolds viscosity model

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.

Automated summary

The impact of radiation and boundary slip on the flow of CNT-Fe3O4/kerosene oil (KO) hybrid nanofluid across a porous exponentially stretching sheet is investigated in this study. The temperature-dependent viscosity is modeled using the Reynolds viscosity model. A comparative analysis is conducted for SWCNT-Fe3O4/KO and MWCNT-Fe3O4/KO. The nonlinear partial differential equations are transformed into non-dimensional ordinary differential equations and solved using the Legendre wavelet collocation technique. The results show enhanced thermal profiles with increased radiation and heat generation, and a superior velocity profile for MWCNT-Fe3O4/KO compared to SWCNT-Fe3O4/KO. The heat transfer rate is found to increase by 30.11% when the volume fraction of Fe3O4 is elevated from 1% to 10%.
