Abstract
Heating profiles and reaction rates, which are crucial in the mixed convection Falkner–Skan flow of nanofluids down a wedge, are strongly influenced by the binary chemical reaction and activation energy. Slower chemical reactions caused by higher activation energy affect concentration layers and heat transmission mechanisms. Heat generation, absorption, flow, and thermal properties are all changed by binary processes. In a variety of technical and industrial applications, their combined effects are crucial in either increasing or decreasing the efficiency of heat and mass transport. The governing equations have been appropriately converted into a set of ordinary differential equations in order to handle these dynamics. The bvp4c scheme in MATLAB software has been used to solve the resulting equations. Skin friction, local Nusselt number, and velocity, temperature, and nanoparticle concentration profiles are discussed and illustrated graphically in the paper. The findings show that increasing the wedge angle parameter increases the nanofluid's velocity, whereas the Darcy number shows the opposite trend.
