We report direct optical observation of cavitation bubbles in liquid helium, both in classical viscous He I and in superfluid He II, close to the $$\lambda $$ -transition. Heterogenous cavitation due to the fast-flowing liquid over the rough surface

An experimental investigation of steady-state thermal counterflow of superfluid ${}^{4}$He indicates that, in the range of investigated parameters, interactions between flow-probing particles and tangles of quantized vortices are appreciably influenc

Thermal counterflow of superfluid 4He is investigated experimentally in the proximity of a 3 mm diameter cylinder by analyzing the motions of micrometer-sized solid particles, focusing especially on the occurrence of macroscopic vortices. The influen

Quantum turbulence in thermal counterflow of superfluid 4He is studied at length scales comparable to the average distance R between quantized vortices. The Lagrangian velocities of micrometer-sized deuterium particles, smaller here than R, are calcu

A quartz fork vibrating at high amplitude is used to study cavitation in He I and He II along the saturated vapor pressure (SVP) curve and at slightly elevated pressures. Cavitation is observed as a breakdown of the resonance response at critical vel
