Unsteady-state rarefaction flows with symmetry

  • O. V. Rysev


The article considers unsteady-state isentropic rarefaction flows having either axial or central symmetry. Using the canonical form for writing the relationships which are satisfied along the characteristics, it is shown that, under determined conditions, rarefaction flows may contain a characteristic along which the velocity and the speed of sound vary as in a flow from some stationary source.
