Quartz Tuning Fork: Thermometer, Pressure- and Viscometer for Helium Liquids
Rob Blaauwgeers,M. Blazkova,M. Človečko,Vladimir Eltsov,R. de Graaf,J. J. Hosio,Matti Krusius,D. Schmoranzer,Wilfried Schoepe,Ladislav Skrbek,P. Skyba,R. E. Solntsev,D. E. Zmeev +12 more
TL;DR: In this article, commercial quartz oscillators of the tuning-fork type with a resonant frequency of ∼ 32 kHz have been investigated in helium liquids and their properties in the regime of linear viscous hydrodynamic response in normal and superfluid 3He and 4He, by comparing measurements to the hydrodynamynamics model of the sensor.
Journal ArticleDOI
Vibrating Quartz Fork—A Tool for Cryogenic Helium Research
M. Blažková,M. Človečko,Vladimir Eltsov,E. Gažo,R. de Graaf,J. J. Hosio,Matti Krusius,D. Schmoranzer,Wilfried Schoepe,Ladislav Skrbek,P. Skyba,R. E. Solntsev,W. F. Vinen +12 more
TL;DR: In this article, the authors review the use of tuning forks as thermometers, pressure-and viscometers as well as their potential as generators and detectors of cavitation and turbulence in viscous and superfluid He liquids.
Journal ArticleDOI
Acoustic Emission by Quartz Tuning Forks and Other Oscillating Structures in Cryogenic 4He Fluids
D. Schmoranzer,M. La Mantia,G. A. Sheshin,I. A. Gritsenko,A. A. Zadorozhko,Miloš Rotter,Ladislav Skrbek +6 more
TL;DR: In this paper, the authors report on experimental investigations of acoustic emission by quartz tuning forks resonating at frequencies 32, 38, 57, 77, and 100 kHz in cold gaseous 4He and its normal and superfluid liquid phases.
Journal ArticleDOI
Crossover from hydrodynamic to acoustic drag on quartz tuning forks in normal and superfluid 4 He
D. I. Bradley,M. Človečko,Shaun N. Fisher,D. Garg,E. A. Guise,Richard P. Haley,Oleg Kolosov,George R. Pickett,Viktor Tsepelin,D. Schmoranzer,Ladislav Skrbek +10 more
TL;DR: In this paper, the authors present measurements of the drag forces on quartz tuning forks oscillating at low velocities in normal and superfluid fluid, and investigate the dissipative drag over a wide range of frequencies, from 6.5 to 600 kHz.
Journal ArticleDOI
Generation of turbulence by vibrating forks and other structures in superfluid H 4 e
TL;DR: In this article, a study of the drag on the prongs of a number of quartz forks vibrating in the superfluid phase is reported, and particular attention is paid to the transitions from laminar to turbulent flow over a wide range of temperature.
