Application of big data analysis technique on high-velocity airblast atomization: Searching for optimum probability density function
(Elsevier, 2020-08-01)
In this paper, the droplet size distributions of high-velocity airblast atomization were analyzed. The spray measurement was performed by a Phase-Doppler anemometer at several points and different diameters across the spray ...
Internal flow characteristics in Spill-return pressure-swirl atomizers
(ILASS, 2019-09-04)
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 ...
Effect of nanoparticles concentration on the characteristics of nanofluid sprays for cooling applications
(Springer, 2019-03-01)
This study addresses the effect of nanofluid synthesis on the rheological properties of the resulting fluid and their consequent effect on the characteristics (size and velocity distribution of droplets, spray cone angle, ...
Selection of model liquid with refractive index matching for visualization of internal flow in a scaled atomizer model
(EDP Sciences, 2019-06-28)
A scaled transparent modular model of pressure-swirl (PS) atomizer was prepared from cast PMMA (Poly(methyl methacrylate), Perspex™, Plexiglas™) with the aim to achieve a better understanding of internal flow and subsequent ...
2D and 3D numerical modelling of internal flow of Pressure-swirl atomizer
(EDP Sciences, 2019-06-28)
This paper compares 2D axisymmetric and 3D numerical models used to predict the internal flow of a pressure-swirl atomizer using a commercial software Ansys Fluent 18.1. The computed results are compared with experimental ...
Investigation of pressure swirl sprays using Volumetric PIV
(ILASS, 2019-09-04)
The volumetric measurement technique (V3V-Flex©) was used to investigate the spray generated by two pressure swirl atomizers (PSAs). Both a simplex pressure swirl atomizer and a spill-return pressure swirl atomizer were ...
Empirical correlation for spray half cone angle in plain-jet airblast atomizers
(Elsevier, 2020-10-01)
Plain-jet airblast atomizers are widely used in industrial applications. The literature contains numerous papers on Sauter mean diameter, however, there is no estimation method available for spray cone angle, SCA, which ...
Effect of liquid preheating on high-velocity airblast atomization: From water to crude rapeseed oil
(Elsevier, 2019-04-01)
Airblast atomization is a suitable model platform to understand atomization physics since the atomizer geometry has an insignificant influence on the spray formation. Besides its theoretical relevance, this configuration ...
