The flow in the tail region of two interacting supersonic streams – spherically symmetrical and planeparallel – is simulated on a supercomputer. The numerical solution is obtained by Godunov’s method. Analysis of the solutions reveals the complex structure of the flow, which includes multiple interfering shock wave structures, a near-axial circulation zone, and a near-axial forward flow zone with a velocity deficit. The detection of such a structure is an unexpected result of the simulation procedure, but it is consistent with some computational and experimental studies, where structures have been observed in supersonic jets.
