Fuel droplet vaporization and spray combustion theory
Abstract
A critical review is presented of modern theoretical developments on problems of droplet vaporization in a high-temperature environment and of spray combustion. Emphasis is placed upon analytical and computational contributions to the theory with some mention of empirical evidence. Four areas of basic phenomena are discussed in some detail: (1) droplet slip and internal circulation, (2) transient heating of the droplets, (3) multicomponent fuel vaporization, and (4) combustion and vaporization of droplet arrays, groups, and sprays. Various relationships amongst these phenomena are analyzed as well. Several other problem areas are given brief mention. Future directions are suggested.
