Consequences of activation energy and binary chemical reaction for 3D flow of Cross-nanofluid with radiative heat transfer

Abstract

In view of ecological concern and energy security, execution of refrigeration system should be enriched which can be done by improving the characteristics of working liquids. The nanoliquids have gained interest in industrial and engineering fields due to their outstanding thermophysical features. Researchers used nanoliquids as working liquid and detected substantial variations in thermal performance. In the present research work, our intention is to explore the impact of nonlinear thermal radiation and variable thermal conductivity on 3D flow of cross-nanofluid. Moreover, heat sink-source, chemical processes and activation energy are implemented. Zero mass flux relation with thermophoresis and Brownian motion mechanisms are scrutinized. The required system of ordinary ones is achieved by implementing appropriate transformations. The achieved system of ordinary ones is computed numerically by implementing bvp4c scheme. Graphs are plotted to explore the impact of various physical parameters on concentration, temperature and velocity fields. It is detected from obtained graphical data that thermophoresis and Brownian motion mechanisms significantly affect heat transport mechanism. Furthermore, graphical analysis reveals that concentration of cross-nanofluid enhances for augmented values of activation energy.

Radiative MHD Nanofluid Flow over a Moving Thin Needle with Entropy Generation in a Porous Medium with Dust Particles and Hall Current

“…He analyzed the influences of entropy and exergy on the presented model and reported that entropy loss enhanced in attendance of stronger magnetic field. Khan et al [ 24 ] examined the numerical solution of 3D cross nanofluid with activation energy and binary chemical reaction with zero mass flux and convective boundary conditions. They noticed that higher estimates of activation energy boosted the concentration of the cross nanofluid.…”

“…In the same direction, Kameswaran et al 32 showed the effect of viscous dissipation in nanofluid flow over a stretching sheet. The combined effect of the radiation and viscous dissipation has been discussed by Makanda et al, 33 Khan et al, 34 and Irfan et al 35 This study focused on the investigation of linear radiation and viscous dissipation on the fluid flow about a vertical cone/wedge/vertical plate implanted in a nanofluid-saturated non-Darcy porous medium. The system of nonlinear partial differential equations is solved using a local linearization technique.…”

Nonlinear mixed convection flow of a tangent hyperbolic fluid with activation energy

“…There are many studies about activation energy in fluid dynamics. Consequently, Khan et al 21 have measured the activation energy of 3D cross‐nanofluid flow with capricious thermal conductivity, nonlinear thermal radiation with chemical processes, and heat sink/source. Sajid et al 22 also examined the incorporation analysis of heat and mass transfer with activation energy, variable thermal conductivity, and nonlinear thermal radiation for Darcy‐Forchheimer flow of a Maxwell nanofluid over a linearly stretching surface.…”
