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.

Thermal System Laboratory

Thermal-Fluid Sciences research efforts at Parks College address a full range of problems, including micro- and nano-scale phenomena and galaxy-sized events. Research efforts are underway to simulate the clouds and large vortices that advect in the atmospheres of Uranus and Neptune. More accurate aerial delivery is under investigation by studying the aerodynamics of parachutes and airdrop systems. In the area of turbomachinery, current work examines aerodynamic losses produced by turbine blades and vanes, the design of internal cooling schemes for such blades and vanes, and the development of improved means for film cooling, as measured within transonic turbine airfoil cascades using infrared thermography. Also of interest are micro-fluidic phenomena, as well as separation, fractionation, and purification of micro-particles and nano-particles. Unmanned aerial vehicles are also under development, including research on improving wing design and controlling aerodynamic flows. Research on the fundamentals of fluid physics examines means to identify the laminar-to- turbulent transition process, as part of investigations on the overall nature of turbulence itself
