Heat Transfer Facilities - SW-6
Turbomachinery Heat Transfer Tunnel
SW-6
Facility Description
This facility conducts aeronautic heat transfer experiments of highly
3-D flow fields in turbomachinery applications. Test sections simulating
turbine flow passages or transition ducts are made of clear plastic
for flow visualization. Test cell air is drawn into a bellmouth,
through the test section, and exits to the altitude exhaust system.
A butterfly valve controls the flow, with flow rates up to 10 lb/s
possible.
SW-6
Special Features
Various flow visualization techniques have been employed in
this facility. Both transient and steady state liquid crystal techniques
for measurement of heat transfer have been used to experimentally
determine heat transfer. Pressure and temperature data is recorded
with a PC based data acquisition system. Image data is recorded
and analyzed with video photography and a PC based image processing
system.
