Effects of Viscous Dissipation and Thermal Radiation on an Electrically Conducting Casson-Carreau Nanofluids Flow with Cattaneo-Christov Heat Flux Model

Abstract

The primary goal of this research is to study the Cattaneo-Christov heat flux model on the impacts of mass and energy transit of MHD Casson-Carreu nanofluid through a permeable vertical accelerating plate with Soret and Dufour mechanism. The non-Newtonian fluids flowed over the porous vertical plate to reach the boundary layer in this investigation. In order to understand the physical model, partial differential equations (PDEs) are used. To get a linked nonlinear set of ordinary differential equations (ODEs), we reduced this set of PDEs by using similarity variables. SHAM, a spectrum basis technique, was utilized to solve these modified equations to understand the physical significance. A good method is to utilize SHAM to decouple the coupled nonlinear ODE systems and divide them into linear and nonlinear equation sets since this helps to separate the systems. As a result, the two non-Newtonian fluids (Carreu and Cassin) flow together through the vertical wall and into the boundary layer, where different parameters’ impacts are scrutinized. The current results showed that an upturn in the Casson parameter (β) degenerates the boundary layer velocity and the total thickness. Upturn in the Weissenberg number (We) on the other hand, raises the velocities and temperatures in both directions. Additionally, increasing the Soret and Dufour parameters sped up the velocity graph.

Impact of Magnetohydrodynamics on Hyperbolic and Walters-B Non-Newtonian Fluids

“…Neffah et al, [5], Eberhard et al, [6], Gomez-Constante and Rajagopal [7], Ionescu et al, [8], and Seybold et al, [9] emphasized a few tremendous research works containing non-Newtonian fluid flow through different geometries. Also, the literature presents numerous constitutive equations to analyse the properties of non-Newtonian fluids [10][11][12]. The model of tangent hyperbolic fluid is sufficient to adequately explain the occurrence of shear thinning.…”

Magnetohydrodynamic bioconvective flow past an elongated surface with convective heat transport, and velocity slip in a non‐Darcian porous regime

“…Famakinwa et al 35 studied thermal radiation with viscous dissipation containing hybrid nanoelements of two oriented sides. Veera Reddy et al 36 presented the effects of energy with mass transit of an MHD Casson nanofluid across a permeable sheet using Cattaneo-Christov heat flux. To get to know how radiation affects MHD-free convective mass transport in viscous flow across a stretchy surface, Nalivela et al 37 conducted investigations.…”
