Decoupling between first sound and second sound in He - superfluid He mixtures
T. S. Riekki, M. S. Manninen, J. T. Tuoriniemi
Bulk superfluid helium supports two sound modes: first sound is an ordinary pressure wave, while second sound is a temperature wave, unique to inviscid superfluid systems. These so…
Surface Waves on Superfluid 3He and 4He
M. S. Manninen, J. Rysti, I. A. Todoshchenko +1
Surface waves on both superfluid 3He and 4He were examined with the premise, that these inviscid media would represent ideal realizations for this fluid dynamics problem. The work…
Measurements on Melting Pressure, Metastable Solid Phases, and Molar Volume of Univariant Saturated Helium Mixture
J. Rysti, M. S. Manninen, J. Tuoriniemi
A concentration-saturated helium mixture at the melting pressure consists of two liquid phases and one or two solid phases. The equilibrium system is univariant, whose properties d…
Quartz Tuning Forks and Acoustic Phenomena - Application to Superfluid Helium
J. Rysti, J. Tuoriniemi
Immersed mechanical resonators are well suited for probing the properties of fluids, since the surrounding environment influences the resonant characteristics of such oscillators i…
