Twin-fluid atomization of viscous liquids: The effect of atomizer construction on breakup process, spray stability and droplet size
This study focuses on the low-pressure spraying of viscous liquids ( = 60, 147 and 308 mPa s) using four types of internal-mixing twin-fluid atomizers.
Effect of nanoparticles concentration on the characteristics of nanofluid sprays for cooling applications
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, ...
An accuracy analysis of the front tracking method and interface capturing methods for the solution of heat transfer problems with phase changes
(IOP Publishing, 2016-06-19)
Materials undergoing a phase change have a number of applications in practice and engineering. Computer simulation tools are often used for investigation of such heat transfer problems with phase changes since they are ...
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 ...
Experimental verification of boundary conditions for numerical simulation of airflow in a benchmark ventilation channel
(EDP Sciences, 2016-03-28)
Correct definition of boundary conditions is crucial for the appropriate simulation of a flow. It is a common practice that simulation of sufficiently long upstream entrance section is performed instead of experimental ...
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 ...
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 ...
Investigation of pressure swirl sprays using Volumetric PIV
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 ...
