Influence of activation energy on triple diffusive entropy optimized time-dependent quadratic mixed convective magnetized flow

Abstract

The flow over a wedge with activation energy and chemical reaction gains widespread applications in compound creations, food processing, insulation, oil reservoirs, catalysis, etc. The vast applicability of activation energy with a binary chemical reaction comprising multiple diffusions and the time-dependent nature of the entropy-optimized flow has drawn our attention to this work. The consequences of time, activation energy, liquid hydrogen and oxygen diffusions, and magnetic field over a wedge in the quadratic combined convection flow with entropy analysis are explored to achieve more mechanically realistic outcomes. The nonlinear dimensional coupled partial differential equations (PDEs) that govern the modelled phenomenon are tackled with non-similar transformations, the Quasilinearization technique followed by an implicit finite difference scheme and Varga’s matrix inverse procedure. The entropy generation can be minimized by upsurging the magnitude of the temperature difference ratio attribute [Formula: see text]. The higher wedge angle results in a lower fluid motion.
