Kavitace v kapalném heliu vyvolaná vibrujícím křemenným krystalem
Blažková, Michaela ; Chagovets, Tymofiy ; Rotter, M. ; Schmoranzer, D. ; Skrbek, Ladislav
An experimental setup containing a quartz tuning fork inside a pressure cell in a glass helium cryostat enables us to experimentally observe effects in liquid He, which we ascribe to cavitation (as these are absent in gaseous He), taking place in the vicinity of the fork. Liquid helium can be prepared extremely clean and wets almost ideally any solid surface – it provides an ideal model system to study cavitation.
Křemenný krystal - frekvenční standard pro digitální hodinky jako citlivý nástroj pro studium proudění mezní vrstvy
Blažková, Michaela ; Chagovets, Tymofiy ; Pešička, J. ; Rotter, M. ; Skrbek, Ladislav
We describe basic properties of commercial quartz tuning forks – frequency standards for digital watches which can be used as a very sensitive pressuremeters, thermometers and furthermore they can generate and detect boundary layer flow of cryogenic fluids.
PIV technique for investigations of cryogenic helium flow
Blažková, Michaela ; Chagovets, Tymofiy ; Rotter, M. ; Schmoranzer, D. ; Skrbek, L.
We describe various aspects of cryogenic PIV technique and give examples of its successful application of various flows of cryogenic helium, with appropriately chosen of tracking particles such as hollow glass spheres, polymer microspheres or solid hydrogen-deuterium flakes.
