A generalized Fourier and Fick's perspective for stretching flow of burgers fluid with temperature-dependent thermal conductivity

Abstract

Original scientific paper https://doi.org/10.2298/TSCI171025082W This research addresses heat generation and mixed convection characteristics inBurgers fluid-flow induced by moving surface considering temperature-dependent conductivity. The novel revised Fourier-Fick relations covering heat/mass paradoxes are introduced simultaneously. Boundary-layer concept is implemented for simplification of mathematical model of considered physical problem. Compatible transformations are utilized to transform partial differential system into ordinary ones. The idea of homotopic scheme is employed to establish convergent series solutions. The mechanisms of heat-mass transportation are elaborated graphically by constructing graphs for distinct values of physical constraints. We noticed higher temperature and concentration for Fourier-Fick situations when compared with revised Fourier-Fick situations. Furthermore, an increment in variable conductivity factor yields higher temperature and related thickness of thermal layer. The obtained results are compared with available literature in a limiting manner and reasonable agreement is found.

Analysis of entropy generation minimization in flow of Ree-Eyring nanofluid between two coaxially rotating disks

“…Inspired by the above literature survey of non-Newtonian fluid over a stretchable surface, the present research work aimed to explore the radiative nanomaterial flow of Ree-Eyring fluid subject to stretchable surface with entropy generation. Series solutions are developed via homotopy analysis method [24][25][26][27][28][29][30]. Furthermore, Heat and mass transfer rates and skin friction coefficient are numerically discussed and presented through tables.…”

A modified Fourier-Fick analysis for modeling non-Newtonian mixed convective flow considering heat generation

“…Characteristics of modified Fourier law for computational analysis of non-Newtonian (Carreau and Jeffrey) material are communicated by Khan et al [12,13]. Waqas et al [14] introduced heat source concept in mixed convective Burgers material subjected to improved Fourier-Fick expression. Variable liquid aspects in stratified Carreau nanoliquid subject to improved Fourier law are examined by Khan et al [15].…”

Significance of improved Fourier-Fick laws in non-linear convective micropolar material stratified flow with variable properties

“…Christov [6] modified Cattaneo model [3] via insertion of upper-convected Oldroyd's derivative. Some researches elaborating flow subjected to Cattaneo-Christov (non-Fourier) heat flux are given in [7][8][9][10][11][12].…”
