Labs and Facilities
Fluid Systems Laboratory
Subsonic Wind Tunnel
There is a 28x40 inch closed-throat, open circuit low speed wind tunnel, that is capable
of continuous air speeds up to 150 mph. A six component strain gauge balance with
computerized data acquisition and analysis using LabVIEW is available. A helium bubble
generator unit is available for flow visualization studies. A Laser Doppler Velocimetry
system is available for flow measurements. This facility is utilized for undergraduate
laboratory instruction. Students and faculty use this facility for model testing and
experimental research. This facility is also used for graduate research as well as
externally funded research.
There is a 12X12 inch closed-throat, open circuit low speed wind tunnel, that is capable
of air speeds up to 120 mph. A four component strain gage balance is available for
measuring forces on a sting mounted model. This facility is primarily used for undergraduate
laboratory instruction.
Supersonic Wind Tunnel
There is a 4x4 inch supersonic blow down wind tunnel with speed to Mach 4. A four
component strain gauge balance and computerized data reduction system is available.
Flow visualization in the supersonic wind tunnel is done through a Schlieren Optical
System. This facility is used primarily for undergraduate laboratory instruction.
Water Tunnel
There is a water tunnel (Eidetics 1520) for flow visualization studies as well as
investigating other fluid flow behavior past bodies. A dynamic model support is available.
This facility is used for undergraduate laboratory instruction as well as graduate
research. A shear layer water tunnel is also available. There exists a state of the
art Digital Particle Image Velocimetry System (DPIV) along with high-speed data acquisition
system for flow visualization & analysis in the two water tunnels.
