Non-Fourier pseudoplastic nanofluidic transport under the impact of momentum slip and thermal radiation

Abstract

In this modern era of research, fluid mechanics and particularly nanofluids flowing on the stretching surfaces are considered to be occurring more often due to their faster heat transfer mechanism. Mostly, the theoretical research related to nanofluids including this one contributed in studying the performance and reaction of nanomaterials against different physical constraints so that they have wide applications in several developed engineering industries like, atomic receptacles, transportation, microchip technology as well as biomedicine industry and food industry. Several fluids permeating in industrial and biological processes are pseudo-plastics. Their non-Newtonian behavior is usually related to structural reorganizations of the fluid molecules due to their flow. Keeping this in view, this study is an effort to investigate two-dimensional steady incompressible Cattaneo–Christov heat flux model of Carreau–Yasuda nanofluid in the presence of thermal radiation and velocity slip. The governed model is presented through partial differential equations which are transformed into ordinary differential equations by using similarity transformation. The final system of equations are solved numerically and the results are expressed through graphs and tables for fluid’s velocity temperature, concentration and physical quantities like heat and mass flux. It is observed that skin friction as well as local heat and mass flux decline with velocity slip parameter and heat transfer rises but mass flux at surface declines through increment in radiation parameter.
