Dynamics of MHD second-grade nanofluid flow with activation energy across a curved stretching surface

Abstract

This analysis addresses the influence of activation energy on the MHD flow of second-grade nanoliquid over a convectively heated curved stretched surface. The impact of heat generation/absorption, thermophoresis, and Brownian motion are also incorporated. This current study in addendum reveals the solution narrating the nanofluid flow behaviour of the stretched curve to better the performance of the system. Hence, the mathematical construction of governing partial differential equations (PDEs) is transmitted into nonlinear ODEs by employing appropriate transformations. The attained ODEs are conducted numerically via ND-Solve. It is consequential to report that fluid velocity and temperature fields significantly rise with concurrent enhancing values of the fluid parameter and curvature parameter. Moreover, the concentration field enhances considering the energy activation variable and suppresses with the reaction rate constant while thermophoresis escalates the temperature distribution as the Nusselt number lowers with a stronger internal heat source parameter Q.

The physical significance of Hall and ion-slip effects on second-grade nanofluid flow over a vertically oriented surface with oscillating free-stream

“…where 1   . Use of equation ( 21) to the equation (17) and BCs in (20) and the comparison of the zeroth-and first-degree terms of  , yield…”

“…This study confirms the augmentation of velocity for second-grade parameter. The hydromagnetic effect on second-grade nanofluid flow across a curved stretching sheet with activation energy is explored by Reddy et al [17] while the second-grade hybrid nanofluid flow over a stretching flat plate with activation energy is discussed in the article of Arif et al [18]. Roy and Ghosh [19] studied the hydromagnetic buoyancy-driven flow of second-grade hybrid nanofluid over a vertical surface and recommended that the large heat dissipation reduce the flow velocity and temperature.…”

Numerical investigation of chemically reacting jet flow of hybrid nanofluid under the significances of bio-active mixers and chemical reaction

“…It has been examined that the energy curve is heightened due to the enrichment of the Eckert number. Reddy et al [ 5 ] have addressed the upshot of the chemical reaction on the nanoliquid flow over curved surface. They simulated their problem with the use of the ND-solver technique.…”

Energy transport analysis in natural convective flow of water:Ethylene glycol (50:50)-based nanofluid around a spinning down-pointing vertical cone

“…With progress in nuclear energy, nanoparticles are also used as coolants in nuclear power plants (Hamidreza Arab BafraniNoori-kalkhoran et al, 2020), in enhancing oil recovery, nano-refrigerants, and nanolubricants (de Carvalho et al, 2020;SahbanAlnarabiji and Husein, 2020;Salari and Seid Mahdi Jafari, 2020;Mallikarjuna et al, 2021), and in turning and grinding processes (SaswatKhatai et al, 2020). In addition to nanofluid, the flow of hybrid nanofluid across a stretched surface has recently been studied (Aly and Pop, 2019;Aly and Pop, 2020a;Aly and Ebaid, 2020;Aly and Pop, 2020b;Aly et al, 2021;Ahmad et al, 2022;Aly et al, 2022;Arafat et al, 2022;Reddy et al, 2022;Usafzai et al, 2022).…”
