SPRAY FLAME CHARACTERISTICS WITH STEAM-ASSISTED ATOMIZATION
Gabriel D. Roy · 2001
Most previous studies have used air as the atomizing uid in air-assist or air-blast sprays [1{5]. Our current level of understanding is only based on atomization using air as the uid. Previous studies have also shown that physical and chemi- cal properties of the gas have a signicant in uence on atomization quality [1, 2]. The atomization gases examined were argon, carbon dioxide, nitrogen, and air. These gases were used to study the eect of gas density and heat capacity on the atomization quality. The eect was examined by maintaining the mass or momentum ux of atomization gas xed to the fuel nozzle. The results showed that maintaining a constant-momentum ux with the dierent gases yields the same size distribution. Enrichment of atomization air with oxygen was also found to have a signicant eect on the ame dynamics and ame radiation characteristics [3].
