Reynolds nano fluid model for Casson fluid flow conveying exponential nanoparticles through a slandering sheet

Abstract

Nanofluids with their augmented thermal characteristics exhibit numerous implementations in engineering and industrial fields such as heat exchangers, microelectronics, chiller, pharmaceutical procedures, etc. Due to such properties of nanofluids, a mathematical model of non-Newtonian Casson nanofluid is analyzed in this current study to explore the steady flow mechanism with the contribution of water-based Aluminum oxide nanoparticles. A stretchable surface incorporating variable thickness is considered to be the source of the concerning fluid flow in two-dimension. An exponential viscosity of the nanofluid is proposed to observe the fluid flow phenomenon. Different models of viscosity including Brinkman and Einstein are also incorporated in the flow analysis and compared with the present exponential model. The physical flow problem is organized in the boundary layer equations which are further tackled by the execution of the relevant similarity transformations and appear in the form of ordinary nonlinear differential equations. The different three models of nanofluid viscosity exhibit strong graphical and tabulated relations with each other relative to the various aspects of the flow problem. In all concerned models of the viscosity, the deteriorating nature of the velocity field corresponding to the Casson fluid and surface thickness parameters is observed.

Radiation effect on stagnation point flow of Casson nanofluid past a stretching plate/cylinder

“…Poornima 20 studied steady two dimensional, immiscible boundary layer stagnation point flow of regular and hybrid CuO + MgO nanoparticles across a stretching/shrinking cylinder. As a result of this, several more analytical and numerical research on the flow of nanoparticles has been widely published, such as in references [21][22][23][24][25][26] .…”

“…The radial velocity as well as pressure in dimensionless representations, are integrated into the solutions in (23) and (24).…”
