NANOFLUID OVER RADIALLY STRETCHING SURFACE WITH TEMPERATURE-DEPENDENT HEAT SOURCE

Abstract

The present study investigates the mass transport, heat, and boundary layer flow properties of an electrically conducting nanofluid across a radially extending surface that is heated by convection.  Such configurations are relevant in industrial and biomedical applications where efficient thermal and mass transport is essential. Similarity transformations are used to convert the governing nonlinear partial differential equations which were generated under the boundary layer into a set of ordinary differential equations. The Runge-Kutta-Fehlberg scheme in conjunction with a shooting approach is used to solve them numerically.  The results reveal that higher viscosity and nanoparticle concentration reduce the heat transfer rate, while stronger Brownian motion and increased Lewis number enhance mass diffusion. This work is groundbreaking since it employs a single modeling framework to tackle several associated physical processes, such as convective boundary conditions, electromagnetic interactions, and nanoparticle dynamics. The results demonstrate the study's scientific value and practical applicability by providing helpful insights for maximizing heat and mass transfer in intricate systems like drug delivery, cooling technologies, and microfluidic devices.
