摘要

Spill-return (SR) atomizers enhance the construction of Simplex atomizers by addition of a passage in the rear wall of the swirl chamber through which the liquid can be spilled away. It allows to discharge the liquid always at a high pressure and to spray well over a wide flow rate range. The spray characteristics of pressure-swirl atomizers are strongly linked to the internal flow, and the air-core dynamics affect the spray stability. The SR atomizers are rarely investigated and their internal flow is not studied at all. Therefore, in this paper, the Simplex and SR atomizers with a central SR orifice were examined comparatively.
