Treatment of sedov’s solution as series intermediate asymptotics in flow from strong blast
Autors:
Chernov Igor Alekseevich, Saratov State University
Abstract:
It is offered to consider Sedov’s self-similar solution which earlier was used for exposition only an initial stage of flow from strong blast, in a role of an intermediate asymptotics of matching flow and for any medial, but not so major moment of time. Thus the index of self-similarity should be increased. The upper border of this range is certain from a condition of a constancy of an entropy behind a shock wave.
