Investigation of binary chemical reaction in magnetohydrodynamic nanofluid flow with double stratification

Abstract

This article addresses MHD nanofluid flow induced by stretched surface. Heat transport features are elaborated by implementing double diffusive stratification. Chemically reactive species is implemented in order to explore the properties of nanofluid through Brownian motion and thermophoresis. Activation energy concept is utilized for nano liquid. Further zero mass flux is assumed at the sheet’s surface for better and high accuracy of the out-turn. Trasnformations are used to reconstruct the partial differential equations into ordinary differential equations. Homotopy analysis method is utilized to obtain the solution. Physical features like flow, heat and mass are elaborated through graphs. Thermal stratified parameter reduces the temperature as well as concentration profile. Also decay in concentration field is noticed for larger reaction rate parameter. Both temperature and concentration grows for Thermophoresis parameter. To check the heat transfer rate, graphical exposition of Nusselt number are also discussed and interpret. It is noticed that amount of heat transfer decreases with the increment in Hartmann number. Numerical results shows that drag force increased for enlarged Hartmann number.

Performance of variable characteristics on MHD Jeffery nanofluid over spinning disk with Cattaneo‐Christov heat flux and microswimmers

“…Masood et al [2] investigated the two dimensional and incompressible MHD non-Darcian stagnation-point flow with Cattaneo-Christov heat and mass fluxes, viscous dissipation, Brownian motion and thermophoresis effects in which the flow is reduced as the Darcy number increases. Anjum et al [3] analyzed the double diffusive stratified MHD nanofluid flow with binary chemical reaction and activation energy under zero mass flux using homotopy analysis method (HAM) for the problem solution. Masood et al [4] used the modified diffusive theory for heat and mass transfer in hydromagnetic flow past a stretching surface where the thermal relaxation time parameter reduced the temperature field and solutal relaxation time parameter decreased the nanoparticles concentration distribution.…”

Nonsimilar modeling analysis of Carreau–Yasuda mixed convective flow in a porous medium subjected to Soret and Dufour influences

“…Different physical phenomenon, ranging from gravitation system to fluid dynamics, are governed by nonlinear partial differential systems (PDEs) and it is difficult to obtain their solutions. Although, similarity technique has been extensively employed in literature [40][41][42][43][44][45][46] to transform the nonlinear PDEs into ODEs, but the technique cannot be used to a significant extent because of some of its limitations. To tackle nonsimilar problems Sparrow and Yu [47] presented the technique of local nonsimialrity.…”

Energy and mass transfer analysis of 3-D boundary-layer flow over a rotating disk with Brownian motion and thermo-phoretic effects

“…Moreover, the energy species transport rate of Casson-type nanoliquid by incorporating chemical impacts was investigated by Panigrahi et al [21]. Anjum et al [22] discussed the chemical reaction effects on nanoliquid flow by the utilization of double stratification. Further, Mondal et al [23] discussed the chemical reaction influence on nanoliquid flow for a stretchable cylinder.…”
