Free convective flow of micropolar nanofluid over a heated stretching sheet with the impact of dissipative heat and binary chemical reactions

Abstract

Enhancing the design and performance of several industrial processes, such as heat exchangers, combustion systems, and chemical reactors, depends heavily on the effects of binary chemical reactions on heat transfer phenomena. The free convective hydromagnetic micropolar fluid moving over a stretching sheet is investigated in this work. The combined action of dissipation and bilateral reaction enhances the flow phenomenon. The implications of thermal radiation, viscous dissipation, and joule heating are included in the mathematical model. The proposed problem generates a system of nonlinear partial differential equations, which are then converted into nonlinear ordinary differential equations. The Runge–Kutta fourth-order approach combined with the Shooting scheme is used to solve these modified ODEs. Various contributing factors were analysed and illustrated through the use of graphic representations. The primary conclusions are: the non-Newtonian micropolar parameter exhibits more notable features in comparison to its Newtonian. Thermal radiation accelerates heat transport, but the magnetic parameter decelerates it.
