Adiabatic spray vaporization with droplet temperature transient

Adiabatic spray vaporization is investigated by analyzing the coupled problem of the vaporization of an ensemble of droplets in a gaseous medium whose properties are continuously being modified by the vaporization process, A criterion on the mixture properties for achieving complete spray vaporization is established. By further showing that the droplet temperature rapidly approaches a constant, characteristic, value after vaporization is initiated, simplified solutions are obtained for the transport of monodisperse, as well as polydisperse, sprays in quasi-one-dimensional chambers.
