Modelling of fluid flow and heat transfer in a reciprocating compressor
(IOP Conference Series, 2015-08-17)
Efficiency of reciprocating compressor is strongly dependent on several parameters. The most important are valve behaviour and heat transfer. Valves affect the flow through the suction and discharge line. Heat flow from ...
Modelling fluid flow in a reciprocating compressor
(EDP Sciences, 2015-05-06)
Efficiency of reciprocating compressor is strongly dependent on the valves characteristics, which affects the flow through the suction and discharge line. Understanding the phenomenon inside the compressor is necessary ...
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 ...
Energy conversion during effervescent atomization
The paper qualitatively describes processes during the internal flow, discharge of two-phase mixture as well as spray formation with a particular focus on the energy transfer during effervescent atomization of light heating ...
