Transient Processes in a Non-Rigid Slurry Droplet During Liquid Vaporization and Combustion

Abstract

In an earlier analysis, matched asymptotic expansions in a parameter representing the ratio of the energy required for liquid heating to that required for liquid vaporization were applied to slurry-droplet combustion for solid loadings sufficiently large that the droplet diameter remains approximately constant. Here that analysis is extended to smaller solid loadings for which the droplet diameter decreases with time during part of the combustion history, and implications concerning burning of pure liquid droplets are drawn.
