Abstract
Main properties of liquid helium regarded as starting points of the model developed in the paper are presented. Thermomechanical balance equations together with the second law of thermodynamics are discussed in the framework of the gradient generalization of the internal state variable approach. A comparison is made between the present model and the Landau's one; moreover, some main physical properties of helium II are analyzed in the framework of the present approach.File in questo prodotto:
