Combined Effects of Binary Chemical Reaction/Activation Energy on the Flow of Sisko Fluid over a Curved Surface

Abstract

In this study, a modified Sisko fluid with Buongiorno model effects over a curved surface was considered. The MHD was applied normally to the flow direction, and the effects of chemical reacted and active energy at the curved surface is also discussed. We chose this pertinent non-Newtonian fluid model since it best represents blood composition, and thus helps us venture into complex blood flow problems. Since the flow is discharged over a curved shape, we therefore commissioned curvilinear coordinates to best portray our envisaged problem. We were also required to define various sundry parameters to make our mathematical equations easily solvable. Mathematical modelling was completed by considering traditional assumptions, including boundary layer approximation. Numerical simulation was conducted using MATLAB solver bvp4c. Several numerical tests were conducted to select the best blend of the linked parameters. We noticed thermal flux upsurged when the chemical reaction parameter was increased with the magnetic indicator parameter caused the flow to slow down, while an increasing amount of activation energy enhanced the concentration of the fluid. The numerical results and impacts of assorted parameters on different profiles are elaborated with the help of graphs and a table.

Unsteady hybrid nanofluid ($$UO_2$$, MWCNTs/blood) flow between two rotating stretchable disks with chemical reaction and activation energy under the influence of convective boundaries

“…In this context, it becomes much important to incorporate chemical reaction effects in order to analyze the flow problem in this study. Other researchers including Hamid et al 24 , Salahuddin et al 25 , McCash et al 26 , Raza et al 27 and Nisar et al 28 explored effects of chemical reaction with activation energy on various non-Newtonian and nanofluid models. Saleem et al 29 studied the effects of chemical reaction on flow of a second-order viscoelastic fluid with heat generation effect.…”

Numerical calculation of unsteady MHD nanofluid flow across two fluctuating discs with chemical reaction and zero mass flux

“…Shuaib et al [41] investigate the nanofluid flow with the magnetic and suction effect. Khan et al [42] and McCash et al [43] discoursed the investigation of MHD 3D second-grade nanoliquid flow across a stretching sheet under the influence of heating joule, slip conditions and thermophoresis. Some remarkable results related to the nanofluid flow are presented by [44][45][46].…”

MHD flow of hybrid nanofluid past a stretching sheet: double stratification and multiple slips effects

“…Fluid flow over a stretching sheet is significant in various industrial and manufacturing processes. For example, fluid processing units operated on roller belts, paper industry and extrusion process, drawing of copper wires, manufacturing of aluminum bottle process, and production of rubber and plastic sheets [3,4]. Devi and Devi [5] studied the flow of hybrid nanofluid over a stretching sheet with suction and magnetic field.…”
