Multicomponent droplet evaporation at intermediate Reynolds numbers

Abstract The convective evaporation of a binary hydrocarbon droplet (decane-hexadecane) in air at 1000 K and at a pressure of 10 atmospheres has been studied using numerical methods. All transient effects including droplet size and velocity variations, heat and mass transfer within the liquid phase, and thermophysical property variations with temperature and concentration in both phases are included in the analysis. As the rate controlling process, liquid phase mass transfer is examined in detail. It is demonstrated that the existing drag coefficient, Sherwood number, and Nusselt number correlations originally developed for single-component droplets can be used for multicomponent droplets as well.
