Establishment of Analytical Model for Peak Temperature Within a Sodium-Water Reaction Jet, (II) : Mean Droplet Size in a Submerged Gas Jet

概要

論文の詳細を見る
This is a second paper that describes work carried out to aid in the development of an analytical model to predict the peak temperature in a sodium-water reaction jet. Specifically, an experimental investigation was performed to determine the effective droplet size (Sauter mean diameter: SMD) in the near field of a submerged jet. A sufficient number of experiments involving jet-airblast atomization of a shallow liquid water layer were carried out to evaluate the effects of injector diameter, injection pressure, orifice submergence and sampling location on the SMD. Despite the scatter in the data believed to be the result of jet unsteadiness, a reasonable correlation for the SMD was achieved by assuming that the submerged jet behaves much like a plain-jet airblast atomizer.
