Purpose – This research peruses the influence of second law analysis for electrically conducting
fluid of a Casson nanofluid over a wedge. For activation energy a modified Arrhenius function is
used.
Design/methodology/approach – The highly non-linear governing equations are developed
using similarity transformations and then computed numerically via Keller box method.
Findings – The influences of emerging parameters on velocity, temperature distribution and
concentration of nanoparticle are explained and presented via graphs and tables. Also the
behavior of fluid flow is investigated through the coefficient of skin friction, Nusselt and
Sherwood numbers. Results reveal that the velocity profile enhances due to increasing Casson
parameter and magnetic parameter, whereas the temperature distribution and concentration of
nanoparticle decrease with larger vales of Casson parameter. It is inspected that the concentration
boundary layer increases due to activation energy and decreases due to reaction rate and
temperature differences.
