Characteristics of Turbulent Particle Transport in Human Airways under Steady and Cyclic Flows 

Jedelský, Jan; Lízal, František; Jícha, Miroslav (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 

Fojtlín, Miloš; Psikuta, Agnieszka; Toma, Róbert; Fišer, Jan; Jícha, Miroslav (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 

Jedelský, Jan; Jícha, Miroslav (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 

Jedelský, Jan; Jícha, Miroslav (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 

Jedelský, Jan; Jícha, Miroslav (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 

Ďurdina, Lukáš; Jedelský, Jan; Jícha, Miroslav (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 

Jedelský, Jan; Jícha, Miroslav (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 ...

Introduction to liquid wall film atomization 

Knotek, Stanislav; Jícha, Miroslav (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 

Tuhovčák, Ján; Hejčík, Jiří; Jícha, Miroslav (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 ...
