• Hydrodynamic aspects of superfluidity
• Multi-temperature mixture of fluids
• Second sound propagation

In this paper, we analyze a multi-temperature model for the description of second sound propagation with an application to superfluid helium. To this aim, we consider a binary inert mixture of Euler%26apos;s fluids and we investigate the case in which the temperatures of the two components are sufficiently close to each other so that a linearization in the neighborhood of an equilibrium state is possible. We also compare the results with those obtained under the single-temperature assumption.
