Abstract

This paper describes mathematical modeling of transport and chemical reaction phenomena in a single droplet on a heated substrate deposited by spray pyrolysis. The droplet contains mixed salt solution which reacts on the heated substrate to produce mixed oxides and water residue. The water is subsequently evaporated, leaving a thin film of the mixed oxides for sensor application. The droplet, containing solvent and precursors is modeled using Computational Fluid Dynamics (CFD) technique. The variety of stages is predicted of the evolution of droplet morphology associated with surface energy and evaporation. The transient distribution is also predicted of the concentration of various species in the droplet. Copyright © 2012 by ASME.
