On cavitation in liquid helium in a flow due to a vibrating quartz fork
Cavitation in normal and superfluid liquid ⁴He at saturated vapor pressure and slightly elevated pressures
 has been experimentally studied in a flow due to quartz forks vibrating at high amplitudes. Above the
 temperature- and pressure-dependent critical velocity, heterogeneous cavi...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Summary: | Cavitation in normal and superfluid liquid ⁴He at saturated vapor pressure and slightly elevated pressures
has been experimentally studied in a flow due to quartz forks vibrating at high amplitudes. Above the
temperature- and pressure-dependent critical velocity, heterogeneous cavitation is observed both visually
and electrically, as a breakdown of the resonance response of the fork.We compare our results with available
experimental and discuss them using existing theoretical models. In particular, we show that thermal effects
leading to local overheating of the vicinity of the fork have to be taken into account, especially in normal liquid
⁴He.
