Abstract.
We study the second sound propagation in superfluid helium using the theoretical background developed in a recent paper [1], through which this phenomenon, both in crystals and in Helium II, can be inserted in a unique framework. In particular, considering an initial rectangular heat pulse and exploiting the selection rules of the physical shocks, a wide phenomenology of travelling shock waves, including the very special case of double shocks, is explained.
