Abstract

The objective of this study is to develop a mathematical model for chemically reacting magnetic nanofluid flow
with thermophoretic diffusion, Brownian motion and Ohmic magnetic heating in a Darcian permeable regime.
The current flow model also considers a number of different nanofluid types i.e. Cu, Ag and Au nanoparticles
with base fluid ethylene glycol. Effectively a nanoscale formulation combining the Buongiorno two-component
model with the Tiwari-Das model is deployed so that a nanoparticle species diffusion equation is also included
as well as material properties for specific nanoparticles and base fluids. By means of similarity transformations,
non-linear dimensionless ordinary differential equations are derived (from the original partial differential
equations) and solved numerically by means of Runge-Kutta-Fehlberg-fourth fifth order method. The effect of
emerging parameters on velocity, temperature, concentration, skin friction, Nusselt number and Sherwood
number profiles is visualized graphically. Validation with earlier studies is included. The computations show
that temperatures are suppressed with greater thermal Grashof and Biot numbers. Nanoparticle-concentrations
are strongly diminished with increasing reactive species and Lewis number, whereas Sherwood number is
elevated with stronger chemical reaction effect. The study is relevant to magnetic nanomaterials processing.
