Dynamical Behaviour of Wall Concentration and Superhydrophobicity Effects on a Combined Reactive Flow in a Slit Microchannel

Abstract

This work shows how Arrhenius-controlled heat and mass transfer flow influenced by uniform wall concentration over a superhydrophobic microchannel is affected by mixed convection with a constant pressure gradient. While the other parallel plate has a no-slip surface (NSS), one of the plates is purposefully altered to have a superhydrophobic surface (SHS). A semi-analytical approach is used for the nonlinear ordinary differential equations. A graphic illustration of the behaviors of the main parameters governing the flow behavior in terms of mass diffusion, temperature, and velocity trends is provided. It was observed that the presence of mixed convection parameter boosts the fluid velocity. Additionally, the symmetric wall concentration effect significantly affects the development of flow reversal. Finally, these findings will find applications in manufacturing processes like hot rolling, drawing of wire, continuous casting, production of glass fiber, and fabrication of paper, cracking in petrochemical engineering, chemical synthesis, anti-wetting micro-technology, etc.
