Abstract
The current paper is on the boundary layer flow of a magnetohydrodynamic nanofluids (Cu, Al2O3 nanoparticles with base fluid water) flow over a linearly stretching cylinder. We have analyzed the entropy generation with heat and mass transfer in mixed convection,
thermal radiation, viscous dissipation, variable thermal conductivity, variable mass diffusivity, and binary chemical reaction with activation energy. Convective boundary conditions are also considered here. No such attempt is yet made by the researchers on hybridization and entropy optimization
model by considering variable thermal conductivity and variable mass diffusivity with binary chemical reaction with convective boundary conditions induced by a stretching cylinder. The efficient implicit Runge-Kutta-Fehlberg method with shooting technique is used for numerical solutions to
the transformed-converted non-linear system of equations. The study is motivated by analyzing the effects on the nanofluid velocity, skin friction coefficient, temperature distribution, Nusselt number, nanoparticles concentration, and Sherwood number inside the boundary layer. The impact of
solid volume fraction, chemical reaction, and activation energy with entropy generation is the key findings of the current investigation. Variable thermal conductivity and variable diffusivity parameters hike temperature and concentration profile, respectively. Entropy and Bejan number are
increasing functions for curvature parameters.
