All three nozzles have axial static pressure tappings allowing the approach, throat and divergent section pressures to be measured. The variation of pressure ratio and mass flow may be investigated for all three nozzles.
Two convergent-divergent nozzles of with the same throat diameter but different discharge area and a single convergent nozzle having the same diameter are supplied and fit in the common test section.
Compressed air regulator for adjusting the pressure downstream of the nozzle
Needle valve on the flow meter for adjusting the back pressure
Nozzle pressure distribution in actual flow of compressible fluids
Instruments: manometer and digital temperature display upstream and downstream of the nozzle as Well as rotameter
Three nozzles with pressure measurement points: 1 convergent nozzle, 1 short and 1 long de Laval nozzle.
