Impact of chemical processes on 3D Burgers fluid utilizing Cattaneo-Christov double-diffusion: Applications of non-Fourier's heat and non-Fick's mass flux models

Abstract

This article communicates the characteristics of Cattaneo-Christov heat and mass flux models on steady three-dimensional flow of Burgers fluid over a bidirectional stretching surface. These models are the modifications of classical Fourier's and Fick's laws through thermal and concentration relaxation times, respectively. Additionally, characteristics of heterogeneous and homogeneous reactions are further investigated. Transformation procedure is adopted to obtain the highly coupled nonlinear ordinary differential equations. The developed nonlinear problem is then solved analytically by utilizing the homotopy analysis method (HAM). The impact of various physical parameters on the temperature and concentration distributions are deliberated and physical characteristics of these parameters are exhibited through graphs and discussed through the reasonable judgment. Our investigation conveys that the temperature and concentration profiles decay as the nondimensional thermal and concentration relaxation time parameters enhances. On the other hand, it is perceived that concentration boundary layer thickness moderates with the growth of Deborah numbers β1 and β2. Additionally, it is fascinating to find that the concentration profiles decline as the Schmidt number escalates. To sum up, the verdict of the present investigation is that the proficiency of thermal and concentration systems can be enriched by introducing the Cattaneo-Christov heat and mass flux models.
