Internal flow characteristics in Spill-return pressure-swirl atomizers
The spray produced by pressure-swirl atomizers strongly depends on the character of their internal flow. Flow field inside a swirl chamber of small pressure-swirl spill-return atomizers was examined using high-speed imaging ...
The influence of spill-line geometry on a spray generated by a pressure-swirl atomizer
(EDP Sciences, 2016-03-28)
An experimental investigation of characteristics of spray generated by a pressure-swirl atomizer (spill-return type) was performed using shadowgraphy and Phase-Doppler Anemometry (PDA). Several different geometries of the ...
Influence of operating conditions and atomizer design on circumferential liquid distribution from small pressure-swirl atomizer
(EDP Sciences, 2017-05-12)
The spray symmetry is an important aspect in most practical applications. However, it is often an overlooked parameter. A measurement of circumferential distribution was carried out by a circular-sectored vessel on several ...
Air–liquid interactions in a pressure-swirl spray
The energy transfer between a liquid hollow cone spray and the surrounding air has been studied using both imaging and phase-Doppler techniques. The spray was produced by a pressure-swirl atomizer discharging Jet A-1 fuel ...
Internal flow and air core dynamics in Simplex and Spill-return pressure-swirl atomizers
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 ...
Flow Behaviour of Inhaled Fibres – Equations of Motion and Preliminary Results of Real Trajectories Recorded by a High-Speed Camera
(EDP Sciences, 2020-11-18)
The ability to precisely predict the fate of inhaled fibres is important for toxicologists as well as for pharmaceutists struggling to utilize fibres as carriers of a medication. However, the complexity of fibre movement ...
