Numerical modeling and analysis of non-Newtonian nanofluid featuring activation energy

Abstract

In this article, activation energy impact in magneto-mixed convective flow of Eyring Powell nanofluid towards a stretched surface is addressed. Nanofluid features are discussed through Brownian motion and thermophoresis effect. Heat transport characteristics are scrutinized through non-linear radiative heat flux and heat source/sink. Furthermore, activation energy and Joule heating effect are also implemented. Zero mass flux condition is imposed at the sheet surface. Appropriate transformations are utilized to reduce the non-linear expressions to ordinary one. Shooting technique is implemented to compute the computational results of non-linear ODEs’ system. Salient attributes of mixed convection parameter, buoyancy ratio parameter, Prandtl number, thermal radiation parameter, Brownian motion parameter, Schmidt number, thermophoresis and Eckert number on velocity, temperature, concentration, surface drag force, and heat transfer rate are examined through graphs and tables. It is scrutinized that nanoparticle volume fraction is reduced via larger Schmidt number while increases when activation energy is incremented.
