Effects of Cattaneo–Christov heat flux analysis on heat and mass transport of Casson nanoliquid past an accelerating penetrable plate with thermal radiation and Soret–Dufour mechanism

Abstract

In this analysis, the effect of Catteneo–Christov model on heat alongside mass transport magnetohydrodynamics of a Casson nanoliquid with thermal radiation and Soret–Dufour mechanism is considered. The fluid flow is considered through porous media as the thermophysical attributes such as viscosity along with thermal conductivity are considered to be constant. Suitable similarity transformations were employed on the governing coupled flow equation to yield total differential equations (ODE). An accurate and newly developed spectral method called spectral homotopy analysis method (SHAM) was employed to provide solution to the simplified equations. The numerical method of homotopy analysis method (HAM) is SHAM. SHAM portrays the division of nonlinear equations into linear as well as nonlinear parts. The findings in this study show that an increment in the Casson parameter is seen to elevate the velocity plot at the wall and lessen the velocity far away from the plate. An increase in the Brownian motion and thermophoresis term is observed to speed up the local skin friction coefficient.

“…The parallel analysis of heat and mass transport through a flowing liquid leads to complications between the energy flux in temperature as well as composition gradient. Contributions of heat transmission over free convection motion of MHD non‐Newtonian liquids were analyzed by Tharapatla et al 14 Reddy et al 15 have explored the contribution of Cattaneo–Christov heat flux of Casson nanofluid flow through an accelerating permeable plate along with radiation, Soret, and Dufour phenomenon.

Steady flow of thin film over porous moving and non‐flat sheet with nonlinear kinematics of exponential type

“…[26][27][28][29]. Several research studies on undermining numerical solutions of unsteady MHD flow heat transfer over a stretching surface with suction or injection are interpreted in miscellaneous research articles [30][31][32][33][34][35][36][37][38][39]. Keeping in view all the above facts a novel problem has been presented and solved.…”

Convective Cattaneo-Christov Heat Flux and Heat Generation Effect on MHD Williamson Fluid Flow Over an Exponentially Stretching Surface With Thermal Radiation

“…Reddy et al [11] studied the two-dimensional viscous flow of Cassson nanofluid with Cattaneo-Christov model and used Spectral Homotopy Analysis Method (SHAM) to get the numerical solution. Ahmad et al [12] investigated the Cattaneo-Christov heat flux model of second-grade nanofluid flow over a stretching sheet and used HAM to get analytic solution.…”
