Measurement of an electronic cigarette aerosol size distribution during a puff
(EDP SCIENCES, 2017-05-12)
Electronic cigarettes (e-cigarettes) have become very popular recently because they are marketed as a healthier alternative to tobacco smoking and as a useful tool to smoking cessation. E-cigarettes use a heating element ...
Prediction of localized aerosol deposition in a realistic replica of human airways using experimental data and numerical simulation
(EDP Sciences, 2016-11-15)
The presence of aerosol deposition hot-spots in human airways presumably contributes to development of various diseases. The overall aerosol deposition in human lungs can be predicted with sufficient accuracy nowadays. ...
Performance of Twin-Fluid Atomizers for Atomization of Viscous Solutions
(EDP Sciences, 2014-11-18)
The article compares the performace of two twin-fluid atomizers with different desing and fluid mixing principles for atomiyation of viscous liquids.
Study of airflow in the trachea of idealized model of human tracheobronchial airways during breathing cycle
(EDP Sciences, 2014-11-18)
Article deals with numerical simulations and its verification by experiments in trachea of idealized geometry of tracheobronchial airways by using unsteady RANS approach. Respiratory cycle was simulated by sinusoidal ...
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 ...
Spray characteristics and liquid distribution of multi-hole effervescent atomisers for industrial burners
The present paper provides an experimental study and optimization of multi-hole effervescent atomizers for industrial burners using oil-based fossil, bio- or waste fuels with prospects of emission reduction. 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 ...
Optimal design of structure in rheological models: an automotive application to dampers with high viscosity silicone fluids
(JVE International, 2017-10-09)
Dynamic torsional vibration dampers are for a long time inherent integral components of internal combustion engines. One of the most common types of the dynamic dampers is a silicone damper. It has been, for many years, ...
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 ...
