Abstract
The novel characteristics of magnetic field and entropy generation in mixed convective flow of Carreau fluid towards a stretched surface are investigated. Buongiornio nanoliquid model consists of thermophoresis and Brownian movement aspects is opted for analysis. Energy expression is modeled subject to thermal radiation and viscous dissipation phenomenon. Concentration by zero mass flux condition is implemented. Consideration of chemical reaction and activation energy characterizes the mass transfer mechanism. Total entropy generation rate and Bejan number is formulated. The utilization of transformation variables reduces the PDEs into non-linear ODEs. The obtained nonlinear complex problems are computed numerically through Shooting scheme. The impact of involved variables like local Weissenberg number, magnetic parameter, thermal radiation parameter, Brownian motion parameter, thermophoresis parameter, buoyancy ratio parameter, mixed convection parameter, Prandtl parameter, Eckert number, Schmidt number, non-dimensional activation energy parameter, chemical reaction parameter, Brinkman number, dimensionless concentration ratio variable, diffusive variable and dimensionless temperature ratio variable on velocity, temperature, nanoparticles concentration, entropy generation, Bejan number, surface drag force and heat transfer rate are examined through graphs and tables.
