Application of TR-PIV Method to Turbulent Flow-Field Studies
The paper deals with conditions of correct application of the Time Resolved ? Particle Image Velocimetry (TR-PIV) method to study a turbulent flow-field. The method is able to catch both spatial and temporal correlation of the veloc...

Preliminary report on machine identification of individual vortices in measured PIV data
Recent research of superfluid He4 shows that the quantum turbulence is indistinguishable from the classical one at the large length-scales, although at small length in the research of classical turbulence. We slowly develop an algor...
