Second-grade fluid with carbon nanotubes flowing over an elongated curve surface possessing thermal radiation and internal heat generation effects

The goal of the current research is to analyze heat transmission of radiative nanofluid with reference to boundary layer nature. Carbon nanotube's (CNT's) reliant liquid is being tested, and it flows on top of a curved extending surface. To scrutinize thermal transmission through the flow additional impacts of thermal radiation as well as internal heat generation have been incorporated. Dual nature of CNTs, that is, single-walled CNTs (SWCNTs) and multi-walled CNTs (MWCNTs) have been employed in conjunction with slurry mixture (base fluid) for the formulation of nanofluid. Second-grade fluid model is engaged in order to capture the rheological properties of slurry mixtures (base fluid). To acquire the numerical solution of designed mathematical model, NDSolve approach is engaged using software Mathematica. Various parameters occurring in governing equations makes an impact on focused physical quantities. Graphs have been employed to capture these impacts for both SWCNTs and MWCNTs. In like manner, the impact of numerous factors on skin friction coefficient as well as Nusselt number have been examined using numerical charts. An increment in dimensionless curvature parameter causes a decline in fluid’s velocity profile as well as temperature profile. However, both fluid’s velocity and temperature get enhanced as an upsurge in solid volume fraction of carbon nanotubes, radiation parameter and heat generation parameter.
