DISPLAY
Transonic flow in a convergent-divergent nozzle is
considered. The throat is situated at one-third of the
length of the duct. The geometry of the nozzle is:
convergent section, inlet area = 1.34; throat area= 1.0
divergent section, outlet area = 1.65.
The inlet Mach number is 0.5, and the design exit Mach
number is 0.6 for which Pexit/Po =0.784.
Consequently, a standing shock wave is created in the
divergent section.
The alteration of the cross-sectional area as a function
of x is provided by means of the east-face porosity factor.
