Characteristics of Turbulent Particle Transport in Human Airways under Steady and Cyclic Flows
(Elsevier, 2012-06-15)
Motion of monodispersed micron-sized particles suspended in air flow was studied on transparent model of human airways using Phase-Doppler Particle Analyser (P/DPA). Time-resolved velocity data for particles in size range ...
Determination of car seat contact area for personalised thermal sensation modelling
(PLOS, 2018-12-11)
A lot of daily activities are conducted in a sedentary posture. This includes a thermal interaction between the human and the seat that has implications on thermal perception and comfort. These interactions are investigated ...
Energy conversion during effervescent atomization
(Elsevier, 2013-09-01)
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 ...
Spatially and Temporally Resolved Distributions of Liquid in an Effervescent Spray
(Begell House, 2012-11-24)
We employed Planar Laser-Induced Fluorescence (LIF) in combination with stereoscopic Particle Image Velocimetry for imaging of concentration and flux fields of liquid phase in an effervescent spray. Light heating oil (LHO) ...
Unsteadiness in Effervescent Sprays: a New Evaluation Method and the Influence of Operational Conditions
(Begell House, 2008-01-01)
A new evaluation method of unsteadiness of the spray generated by an effervescent atomizer is presented. The method is based on measurements of pressure fluctuations in the atomizer mixing chamber. Measurements, made under ...
Investigation and comparison of spray characteristics of pressure-swirl atomizers for a small-sized aircraft turbine engine
(Elsevier, 2014-08-08)
The quality of liquid fuel atomization highly affects the formation of gaseous pollutants and particulate matter emissions from combustion processes. Spray characteristics of two geometrically different pressure-swirl ...
Energy considerations in spraying process of a spill-return pressure-swirl atomizer
(Elsevier, 2014-11-01)
The work focuses on energy conversion during the internal flow, discharge and formation of the spray from a pressure-swirl (PS) atomizer in the simplex as well as spill-return mode. Individual energy forms are described ...
Evaluation of Steadiness and Drop Size Distribution in Sprays Generated by Different Twin-Fluid Atomizers
(EDP Sciences, 2014-11-18)
Dvoumédiové trysky prodělaly značný vývoj v posledních desetiletích. Jsou běžné v mnoha průmyslových aplikacích jako rozprašování paliv, rozprašování tavenin a v potravinářství. Tento článek se soustředí na zhodnocení ...
Introduction to liquid wall film atomization
(EDP Sciences, 2012-04-16)
The objective of the article is an introduction to the theoretical study of atomization of droplets from the surface of a thin liquid film. The overview of basic principles of atomization prediction is complemented by the ...
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 ...
