Impact of the Cattaneo‐Christov thermal and solutal diffusion models on the stagnation point slip flow of Walters' B nanofluid past an electromagnetic sheet

Abstract

The present study investigates the effect of Cattaneo‐Christov thermal and solutal diffusion on the stagnation point flow of Walters' B nanofluid past an electromagnetic sheet subject to velocity, thermal, and solutal slips. The study analyzed the role of electromagnetic fields. In addition, the authors introduced the heat transfer aspect due to Brownian motion and thermophoretic force. The numerical solution of the transformed governing equations employed the spectral local linearization method. Comparisons showed an excellent agreement with the numerical data presented in previous notable works. The study reveals that the developed electromagnetic field due to the arrangement of the sheet causes accelerated fluid motion, and diminution of nondimensional temperature and concentration. In addition, augmented velocity, thermal, and solutal slips develop the corresponding descending boundary layers. The augmented short memory coefficient enhances the skin friction coefficient. The Cattaneo‐Christov thermal and solutal diffusion upsurge the heat and mass transfer rates from the electromagnetic sheet, respectively.

Slip boundary condition effect on double‐diffusive convection in a porous medium: Brinkman Model

“…A number of theoretical and empirical studies in the past few decades have focused on convection in the fluid layer with two or more stratified agencies, cf. [1][2][3][4][5][6][7][8][9][10] The convection caused by the selective absorption of radiation was shown experimentally by Krishnamurti 11 for a viscous fluid. In this experiment, a layer of water comprising a diluted solution of thymol blue (a pH indicator) is utilized.…”

Entropy minimized MHD microrotations of Cross nanomaterials with cubic autocatalytic chemical reaction

“…NLTR appears in nuclear reactors and rocket propulsion. The works of Nayak et al 39,40 show the influence of NLTR on various aspects of BLF subject to different conditions, such as partial slip, convective boundary condition, Cattaneo-Christov heat flux theory, activation energy, and so forth. Almakki et al 41 developed a nanofluid model for entropy generation (EG).…”

Double dispersed bioconvective Casson nanofluid fluid flow over a nonlinear convective stretching sheet in suspension of gyrotactic microorganism

“…Moreover, nanofluid flow finds application in medical science and engineering, for example, peristaltic flow, 8‐10 motion of cilia, 11 generator system, 12 and so on. Walter's B nanofluid flow past an electromagnetic sheet has been discussed by Nayak et al 13 with the impact of Cattaneo‐Christov thermal and solutal diffusion. The present problem deals with the base fluid as Casson fluid, which is a special kind of non‐Newtonian fluid with yield stress, and due to rheological features, it is classified as one of the most accepted non‐Newtonian fluid 14‐17 .…”
