Preliminary computational study of turbulent flow in the boundary layer of the suction side of an inclined plate

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...

Liquefied extinguishing agent discharge to an overpressure-sensitive enclosed volume

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 ...

Analysis of Phenomena Affecting Thermal Measurement on a Test Radial Compressor

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...

Analýza nejistot měření tepelných veličin v odstředivém kompresoru

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...
