Heat Transfer Facilities - SW-2
Transition Duct Heat Transfer Tunnel
SW-2
Facility Description
This facility conducts experiments to acquire and analyze benchmark
experimental maps of heat transfer and flow field in a class of
generic transition ducts and nozzles. The test rig is connected
through valves and piping to the central altitude exhaust system.
Test cell air is drawn into the rig through a bellmouth and flow
conditioning. Air then passes through the Plexiglas walled test
section and exits through a 12-in. diameter pipe and through a fast
opening valve to altitude exhaust. Flows up to 15 lb/sec can be
achieved with a maximum Mach Number generally aroughd 0.5.
SW-2
Special Features
Transient and Steady State Liquid Crystal techniques for measurement
of heat transfer are used. Video photography and PC based image
processing are used to record and analyze liquid-crystal data. Aeodynamic
data, including pressure surveys, boundary layer profiles and free-stream
turbulence can also be collected. Presure and tempeature data is
recorded and a PC based data acquisition system.
