Waves propagation in superfluid helium in presence of combined rotation and counterflow

Rosa Anna Peruzza, Michele Sciacca

Abstract


Using the linear macroscopic mono-fluid model of liquid helium II, in which the fundamental fields are the density ?, the velocity v, the temperature T and heat flux q and taking into account the expression of an additional pressure tensor P(w), introduced to describe phenomena linked to vortices, a complete study of wave propagation is made in the complex situation involving thermal counterflow in a rotating cylinder.
