|  | This is the  
"turbulent boundary-layer generator," a subsonic open-circuit wind 
tunnel designed and built by Rocketdyne for optical studies of 
turbulent wall-bounded flow at the AF Phillips Laboratory Starfire 
Optical Range.  This wind tunnel is a gift to UNM from the 
Phillips Lab.  Nominal design velocity is 18 m/s through the 
50 cm (high) by 10 cm (wide) test section which is 3 m long.  
The maximum flow Reynolds number is of order 106 per meter.  
Silicon rubber heating pads are attached to the aluminum walls 
in the upstream part of the test section; the temperature of 
each wall may be controlled separately.  Optical-quality windows 
(13 and 35 cm) are installed in the downstream portion of the test 
section to allow optical measurement of the flow field. 
Thermal anemometry and laser-based diagnostic systems are used
for flow studies. |
