This study investigates chemical reaction
and thermal radiation effects on hydromagnetic nanofluid flow over an
exponentially stretching sheet. The governing partial differential equations
were transformed to ordinary differential equations by using similarity
transformation and the resulting equations were solved using asymptotic series
method. Graphical results showing the influence of the governing parameters on
the velocity, temperature and concentration are displayed. Our results
indicated that an increase in stretching sheet, thermal Grashof parameters
leads to the increase in the rate of fluid flow while it decreases when
magnetic field factor is increased. Also, increasing the thermophoresis number
brings about increase in temperature and concentration while the reverse is the
case as Prandtl number, Schmidt factor and chemical reaction rate increases.
Increase in radiation leads to increase in the temperature.
