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 ...

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 ...

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 ...

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 ...

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 ...

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 ...

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 ...

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, ...

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 ...

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 ...
