Axisymmetric-conical and locally conical flows without swirling

Axisymmetric steady conical and locally conical non-swirled flows of an ideal (inviscid and non-heat-conducting) gas are considered. Like two-dimensional conical flows, the examined one-dimensional (axisymmetric) flows can be conically subsonic and supersonic. If the uniform flow is not considered as a conical flow, then the type of one-dimensional conical flows can change only on the shock wave, except for the junction of two one-dimensional conical flows of different types on the $C^+$-characteristic. $C^\pm$-characteristics and streamlines are constructed for a number of locally conical flows and some already known and new conical flows.
