In the framework of extended thermodynamics, we consider a model describing a compressible and isotropic non-Newtonian fluid, neglecting heat effects For simplicity we consider the governing equations in the particular case of cylindrical symmetry and look for the propagation of weak discontinuities, comparing the results with those for classical fluids Moreover, under suitable conditions, the system under investigation proves to be invariant with respect to the dilatation group of transformations so that it is possible to characterize similarity solutions Some constitutive relations are characterized for the phenomenological parameters
