A turbulent flow behind a simple thin planar air foil with rounded edges at moderate angle of attack is studied. Reynolds number is about 65 000. First results of CFD analysis are presented, which will be validated with PIV measurements made by Institute of Thermomechanics...

The throttling of liquefied substances from high pressure vessels to an enclosed volume starting at atmospheric pressure is described in order to determine thermodynamic state of the extinguished room gaseous contents. Time dependent, 0D mathematical model is implemented describing the state ...

The Darina IV test equipment is used to determine the characteristics of the radial compressor stages. The pressures and temperatures of the flowing air are measured in several measuring planes. While analyzing the measured results, there was a suspicion regarding of the thermal infl...

The paper is focused on flue gas flow simulations in a first stage filter with top inlet that is used in a cogeneration power plant. CFD simulations were done with emphasize on the influence of inlet chamber on the flue gas distribution and filtering process. The flo...

Compressor performance characteristics evaluation process based on the measurement of pressure, temperature and other quantities is examined to find uncertainties for directly measured and derived quantities. CFD is used as a tool to quantify the influences of different sources of uncertainty...
