Abstract

Motivated by emerging technologies in nanofluid electromagnetic sensor systems, a
mathematical model is developed for free convective chemically reacting magnetized
Buongiorno nanofluid flow along a stretching exponential Riga plate with dual (thermal and
solutal) stratification. Additionally, the effects of radiative heat flux and thermal
sink/generation are included. The non-dimensional boundary layer conservation equations are
solved with the associated boundary constraints using the Keller Box finite difference scheme,
and authentication with earlier studies is conducted. With increasing magnetization parameter,
velocity is elevated whereas temperature is suppressed. Increasing Grashof number enhances
velocity strongly near the sensor surface region but reduces it further towards the free stream. The heat transfer is depleted throughout the boundary layer regime with greater Grashof
numbers. The thermal distribution is substantially boosted with increment in radiative flux,
heat source, thermophoresis and Brownian motion parameters, whereas it is strongly decreased
with increment in Prandtl numbers and thermal stratification. The nanoparticle concentration
is markedly reduced with rising nanoparticle solutal stratification, Brownian motion parameter,
reacting species term and Schmidt number. However, there is a considerable increment in
nanoparticle concentration with high thermophoresis values. An increase magnetization
parameter also elevates the drag force and wall heat transfer rate whereas it reduces the species
gradient at the wall. With increasing chemical reaction, a weak rise in the wall friction and
temperature gradient is noticed, but a significant rise is computed in Sherwood number.
