Similarity Solutions and Strong Shocks in Extended Thermodynamics of Rarefied Gas

We consider the equations of a monoatomic gas, in the context of the extended thermodynamic theory, with spherical symmetry and we look for similarity solutions. The classical problem of the point explosion is considered in order to get some qualitative information due to the presence of the heat flux and the dissipation.It seems that, despite to the classical case, a sub-shock formation cannot be avoided.
