| Abstract: | The two-dimensional axisymmetric problem of the passage of a plane shock wave through a thermal is investigated. Two known effects are confirmed, namely, the intense distortion of the shock front on passage through the thermal and a change in the geometry of the gaseous element characteristic of the late stage of evolution of the thermal. Certain new effects are also detected: the formation of a pendant shock at the outer edge of the hot zone, cumulation of a secondary shock on the axis of symmetry at the top of the thermal, and straightening of the distorted front as it travels away from the heated zone.Translated from Izvestiya Akademii Nauk SSSR, Mekhanika Zhidkosti i Gaza, No. 1, pp. 96–100, January–February, 1988. |
