The University of Florida Research and Engineering Education Facility (REEF) Unsteady Fluid Dynamics Group recently designed and installed a Supersonic Wind Tunnel. The purpose of the facility is to provide supersonic flow conditions for performing research on active and passive control techniques of cavity flows. Research will be conducted using surface pressure measurements, Schlieren and planar optical flow measurement techniques such as Particle Image Velocimetry. The initial nozzle was constructed for M=1.4 flow providing approximately 200 s of run time at a stagnation pressure of 137.9 kPa. Several static and stagnation pressure measurements have been recorded including streamwise and span-wise pressure gradients along with bottom and side wall boundary layer profiles. Imaging of the compressible flow field was accomplished using a classical Z-Schlieren arrangement providing qualitative information of the reflected Mach waves.
