Physical conception of a vortical nature of turbulence
Jonáš, Pavel
The principal ideas on turbulent flows, on vortex structure of turbulence, main attributes of turbulence and on the important features of turbulence at high Reynolds number are presented in the paper.
Thermoanemometer - capabilities and limits of application
Jonáš, Pavel
The fundaments of the hot-wire anemometry together with the analyse of the capabilities and limits are presented.
Characteristics of a HW X-probe at an universal orientation in an air flow
Mazur, Oton ; Uruba, Václav
Considering general orientation of the X hot-wire probe in an air stream expressions for the effectiv cooling velocities of both wires (in JőrgensenŽs form) was derived and proper calibration procedure described
Nestability při interakci paprsku s hlavním proudem
Uruba, Václav ; Mazur, Oton ; Jonáš, Pavel
The results of experimental investigation of the jet in cross flow mixing zone are presented. Used methods allow to determine instabilities in the flow.
3D flow structure influence on X-probe measurements
Uruba, Václav ; Mazur, Oton ; Jonáš, Pavel
In the paper the influence of the velocity component perpendicular to the x-probe plane on results precision is discused. The study is based on experimental results.
Application of CTA measurement in steam turbines
Jonáš, Pavel
A hot-wire method of measurement in a water steam flow using a wire which was not calibrated is described in the paper.
On the arrangement of turbulence measurement at the working section of an intermittently operating wind tunnel
Jonáš, Pavel ; Mazur, Oton
The problem of arrangement of the hot-wire measurement at an intermittently working wind tunnel is discussed with the special regard to the time varying temperature.
On the method of big droplets indication in a wet steam flow using the hot wire anemometer
Uruba, Václav ; Jonáš, Pavel
Some aspect of method of indication of big droplets in a wet steam flow are studied in detailes In the presented paper. Results contribute to physical interpretation of obtained results.
Effect of the power change on time averaged characteristics of the steam flow downstream the LP stage of the 210 MW turbine
Jonáš, Pavel ; Mazur, Oton ; Uruba, Václav
Preliminary results of hot-wire anemometer measurements are presented that were performed in wet steam flow downstream the LP stage of the turbine TG21 in Prunéřov II at the power 210 MW and 140 MW.
A new method of measurement of some statistical moments of velocity and concentration in a stream of two-components gas mixture
Mazur, Oton
System of equations is derived for the calculations of mean values, covariance and variance of the longitudinal velocity component and the admixture concentration in a binary gases mixture.
