Abstract
heat transfer of nanofluids. This study investigates the effects of three different chemical reactions—Arrhenius, bimolecular, and sensitized
reactions—using Buongiorno’s model. Through similarity transformations, the system of partial differential equations (PDEs) is converted
into ordinary differential equations, which are then solved by combining the shooting method with the Runge–Kutta–Fehlberg numerical
technique. The findings show that the skin friction coefficient is greatly increased by raising the pressure gradient and stretching/contracting
wedge parameters. On the other hand, as the thermophoresis parameter, Brownian motion parameter, activation energy, and Lewis number
increase, the Nusselt number decreases, signifying a decrease in the efficiency of heat transfer. A higher Sherwood number, on the other
hand, indicates increased mass transfer and is brought about by increases in the Lewis number, thermophoresis parameter, activation energy,
and Falkner–Skan power-law parameter. These findings provide important information for maximizing heat and mass transfer in nanofluid
systems. Key values for the skin friction coefficient, local Nusselt number, and the Sherwood number are given in tabular form, and the results
are graphically represented.
