Numerical simulation of Joule heating and Arrhenius activation energy for nonlinear radiative flow of Casson nanofluid with Cattaneo–Christov heat flux model

Abstract

This article explores the novel features of Cattaneo–Christov heat flux model for nonlinear radiative flow of Casson nanofluid over an inclined permeable stretched cylinder with joule heating mechanism. The novelty of the present study is to account for the effect of activation energy, dual stratification, nonlinear mixed convection, non-uniform heat generation/absorption, binary chemical reaction and Joule heating effect. The velocity and thermal slips are also accounted for present flow model instead of no-slip condition. Casson fluid nanomaterial model is measured that refers to the significant slip mechanism such as Brownian and thermophoresis diffusions. Suitable similarity transformations are employed to get the required coupled ODEs system. The developed nonlinear system is unravelled through shooting technique along with Runge–Kutta–Fehlberg (RK-45) approach. Physical quantities of interest are investigated through graphs and tables. From the present analysis, we will see the conflicting effect of chemical reaction parameter to that of activation energy parameter Further it will be also analyzed that the heat transfer rate at the cylindrical surface and thermal boundary layer thickness enhances within the frame thermal radiation It will also be observed that both thermophoresis and activation energy parameter become a source of enhancement in concentration frame. A validation of the work is offered by comparing the current results with published literature. Casson flow model as deliberated in the paper finds practical applications in polymer engineering, blood flow, silicon suspensions, and lithograph industry.
