Homogeneous–Heterogeneous Chemical Reactions of Radiation Hybrid Nanofluid Flow on a Cylinder with Joule Heating: Nanoparticles Shape Impact

Abstract

The current analysis aims to exhibit the nanoparticles of Al2O3 + Cu-water hybrid nanofluid flow for Darcy–Forchheimer with heterogeneous–homogeneous chemical reactions and magnetic field aspects past a stretching or shrinking cylinder with Joule heating. This paper performed not only with the hybrid nanofluid but also the shape of Al2O3 and Cu nanoparticles. The model of single-phase hybrid nanofluid due to thermophysical features is utilized for the mathematical formulation. In the present exploration equal diffusions factors for reactants and auto catalyst are instituted. The system of governing equations has been simplified by invoking the similarity transformation. The numerical computations are invoked due to the function bvp4c of Matlab, with high non-linearity. Numerical outcomes illustrated that; sphere shape nanoparticles presented dramatic performance on heat transfer of hybrid nanofluid movement; an opposite behavior is noticed with lamina shape. The local Nusselt number strengthens as the transverse curvature factor becomes larger. In addition, the homogeneous–heterogeneous reactions factors lead to weaken concentration fluctuation.

Enhanced thermal effectiveness for electroosmosis modulated peristaltic flow of modified hybrid nanofluid with chemical reactions

“…Since the Schmidt number characterizes the flow of a liquid in which various processes of mass diffusion and momentum diffusion occur. This trend is in accordance with the Alarabi et al 22 . Thus, higher Sc values reduce the rate of mass diffusion, which leads to the particles to scatter and thus a decrease in concentration is seen.…”

“…Further, a simple template for the interaction between a heterogeneous (or surface) reaction and homogeneous (or bulk) reaction in which two chemical species A and B are presumed. A homogeneous reaction can be expressed by cubic autocatalysis, given by the 22 : and that the heterogeneous reaction is 22 ,

Physical intuition of entropy generation in a mixed convective hybrid nanofluid flow with chemical reaction, cross‐diffusion, and transpiration

“…A shooting technique with the R-K fourth-order integration scheme is used to indecision the converted equations (nonlinear ODEs) ( 10)-( 11) and ( 13) with the boundary conditions (12). Results are displayed through diagrams and tables in dual cases of HBNs: (i) methanol + hematite + magnetite nanoparticles and (ii) blood + hematite + magnetite nanoparticles.…”

“…Bala Anki Reddy et al 6 presented the physical exploration of a homogeneous and heterogeneous chemical reaction using MoS 2 nanoparticles in oil. For a description of a few more, researchers [7][8][9][10][11][12] have revealed that nanofluids showcase superior thermal enactment. The dispersion of solid nanoparticles in a base fluid (nanofluid) have enormous applications in modern sciences.…”

Spectral Relaxation Methodology for Chemical and Bioconvection Processes for Cross Nanofluid Flowing around an Oblique Cylinder with a Slanted Magnetic Field Effect

“…Liu et al [12] looked at a stretching cylindrical surface with chemical reaction as well as the bio-convection and a radiative (nonlinear term appearing in it) Maxwell type nanofluid flow in a Darcy-Forchheimer (porous) medium. Alarabi et al [13] demonstrated the hybrid nanofluid convection for Darcy medium with the involvement of heterogeneous-homogeneous chemical processes and magnetic impact characteristics past an extending or contracting cylindrical surface with the impact of Joule heating using Al 2 O 3 + Cu nanoparticles. Other recent studies related to chemical process with different facts such as activation energy and bi-convection Carreau nanofluid flow, stability of convection in a non-Newtonian vertical fluid, the Electroosmosis forces EOF-driven boundary layer flow, oxytactic microorganisms and nanoparticles, and the bio-thermal convection of Prandtl nanofluid have been made by [14][15][16][17][18].…”
