ABSTRACT: The problem of a supersonic axisymmetric stream in an
environment of higher
pressure is investigated by a method which accounts
fortsubsonic-flod(near the :symme-
try axis. The problem is characterized by a density
discontinuity a- the nozzle. Cy-
lindrical coordinates am used with tho Mach number of the free
stream, relative heat
capacity and relative pressure referred to ambient conditions as
parameters. The com-
putation method first determines the point where density
discontinuity branches out
into one going toward the free streamlines and the other toward
the axis of symnetry.
This method of characteristics is used to integrate the
equations of motion. The com-
putations werv made for the reference Kach number of 2.8 and 3.2
for various ratios of
pressures. The comparison of numerical. computaticns with the
experimental data proves
the effectiveness of the method used f:ir the determination of
the structure of 'the ini-
tial section of'such an axisymmetric stream. Orig. art6 has: 3
