Viscous dissipation and chemical reaction effects on MHD nanofluid flow over a vertical plate in a rotating system

Abstract

Most fluids used in industries possess a constant velocity acting with them. In spite of the fact that there have been a few studies conducted on the topic, the study of fluid flow at a constant velocity using nanofluids is still relatively unexplored. The novelty of this work is the analysis of the heat, and mass transfer of the nanofluid Al 2 O 3 -H 2 O along with a constant velocity in a rotating system with Soret-Dufour effects. This article aims to investigate the MHD nanofluid flow in a vertical plate with a porous medium taking into account viscous dissipation, Joule heating, and a non-uniform heat source/sink. The investigation is subject to steady-state incompressible flow through a vertical plate with a magnetic field and chemical reaction effects. Equations pertinent to nanofluid flow have been modeled as nonlinear partial differential equations. These equations are reformed as nondimensional ODEs utilizing suitable similarity transformations. Employing, the Runge-Kutta method the system of ODEs is solved. The physical impacts of the fluid parameters on velocity, temperature, and concentration are illustrated clearly using graphs. Tables are utilized to present the rate of heat, mass transfer as well as the skin-friction coefficient. A limiting case of our work compared with the existing literature to validate our results. Our results show that when rotation parameter rises from 4 to 6, it decreases the heat transfer rate by 10.8% and mass transfer rate by 5.9%.

Effect of radiation and viscous dissipation using the Galerkin method over a vertical porous plate with variation in temperature

“…Balla and Naikoti et al 31 explained the changes of Soret and Dufour. Analytical solutions for heat, first-order homogeneous chemical reactions, and mass flux have been mentioned by Ibrahim et al 32 Sowmiya and colleagues [33][34][35] discussed the Soret and Dufour effects on MHD nanofluid taking into consideration viscous dissipation, Joule heating, and a nonuniform heat source/sink. Seth et al 36 reviewed a nonsteady impermeable and optically thick fluid past an erratically proceeding vertical plate with increased temperature in a permeable channel, of a Hall current and thermal dispersion.…”

Effects of second order chemical reaction on MHD forced convection Cu, Ag, and Fe3O4 nanoparticles of Jeffrey Nanofluid over a moving plate in a porous medium in the presence of heat source/sink

“…Additionally, recent studies have covered the magnetic effects in nanofluid flow, according to certain useful publications. [24][25][26][27][28][29][30][31][32][33][34][35][36][37][38][39][40] The current study is focused on the second order chemical reaction on the magnetohydrodynamic flow of a water-based Jeffrey nanofluid containing Copper, Silver, and Ferrous Ferric Oxide nanoparticles over a moving stream embedded in a porous medium in the presence of a heat source/sink, and is motivated by the literature review mentioned above. MATLAB's built-in solver, bvp4c, is used to numerically solve the boundary layer equations, and the results are displayed graphically.…”

A Vertical Surface Flow Analysis of MHD Nanofluids Influenced by Radiation, Viscous Dissipation, and Joule Heating with Soret and Dufour Effects

“…Mat et al [19] explored a horizontal channel with thermal radiation, Soret, and Dufour effects on the flow of the Jeffrey fluid. Chemical reactions on the flow of MHD nanofluid with viscous dissipation across a vertical plate in a rotating system were analyzed by Padmaja et al [20]. Ghachem et al [21] and Kumar et al [22] scrutinized the viscoelastic fluid's Soret and Dufour features as caused by viscous dissipation in a moving cylinder.…”
