Analysis of local moisture increase of timber constructions on ice arena roof 

Žák, Antonín; Šikula, Ondřej; Trcala, Miroslav (Trans Tech Publications, 2013-01-08)
Timber is one of the most used materials for roofing of ice arena because of its very good mechanical properties and low weight. High relative humidity of internal air, low temperature and ice rink presence, which cause ...

CFD Simulation of Defogging Effectivity in Automotive Headlamp 

Guzej, Michal; Zachar, Martin (MDPI, 2019-07-01)
In the past decade, the condensation of internal air humidity in automotive headlamps has become more prevalent than ever due to the increased usage of a new light source—LEDs. LEDs emit far less heat than previously-used ...

Turbulence Models for Simulation of the Flow in a Rotor-Stator Cavity 

Zemanová, Lucie; Rudolf, Pavel (EDP Sciences, 2019-06-28)
Modelling of the flow in the cavities between a rotor and a stator is a task of great engineering interest. Correctly evaluated pressure and velocity field enables calculation of the disk losses and therefore assessment ...

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 ...

Internal flow and air core dynamics in Simplex and Spill-return pressure-swirl atomizers 

Malý, Milan; Jedelský, Jan; Sláma, Jaroslav; Janáčková, Lada; Sapík, Marcel; Wigley, Graham; Jícha, Miroslav (Elsevier, 2018-08-01)
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 ...

Study of airflow in the trachea of idealized model of human tracheobronchial airways during breathing cycle 

Elcner, Jakub; Lízal, František; Jedelský, Jan; Jícha, Miroslav (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 ...

Modelling of fluid flow and heat transfer in a reciprocating compressor 

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

Numerical simulation of air flow in a model of lungs with mouth cavity 

Elcner, Jakub; Lízal, František; Jedelský, Jan; Jícha, Miroslav (EDP Sciences, 2011-11-22)
The air flow in a realistic geometry of human lung extended of mouth cavity is simulated with computational flow dynamics approach as stationary inspiration. Geometry used for the simulation includes mouth cavity, larynx, ...

Application of Computer Graphics Flow Visualization Methods in Vortex Rope Investigations 

Urban, Ondřej; Kurková, Michaela; Rudolf, Pavel (MDPI, 2021-01-26)
Computer graphics visualization techniques for application on data from Computational Fluid Dynamics (CFD) simulations of the vortex rope, a phenomenon present in hydraulic turbines operating in off-design conditions, were ...

Simplified approach for creep evaluation in superheaters 

Naď, Martin; Lošák, Pavel; Létal, Tomáš; Pernica, Marek (IOP Publishing, 2020-04-01)
This paper is focused on the estimation of temperature distribution on superheater tube bundles for the consequent creep damage evaluation. The precision of estimated temperatures is very important because it significantly ...
