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’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.

Abstract
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’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.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
