DISPLAY
The problem considered is an axisymmetric, supersonic under-
expanded rocket exhaust plume discharging into a subsonic moving
air stream. The case is the same as library 911, except that
here parabolic marching solution is obtained in a single sweep
using the IPARAB=5 option, rather than an elliptic multi-sweep
solution.
The exhaust gas has a specific-heat ratio of 1.21, a Mach number
of 2.39, a total pressure of 5.786MPa, and a total temperature of
3462 K.
The free-stream has a Mach number of 0.029, a static temperature
of 288K, and a static pressure of 1.01325 bar. The nozzle-to-
ambient static pressure ratio is 3.8.
