A new underwater Stereoscopic Particle Image Velocimetry (SPIV) Torpedo system was designed and constructed at the Naval Surface Warfare Center, Carderock Division for testing in the David Taylor Model Basin. The purpose of the work was to conduct a shakedown test of the new SPIV system to ensure it properly captured SPIV images, and successfully resolved both the in- and out-of-plane velocity fields. To test the system, SPIV measurements were taken on the free-stream flow in the basin and the canonical flow field produced by a circular cylinder at Reynolds numbers around 100,000. After successfully measuring the flow fields, cylinder results were compared to large eddy simulation results that were obtained using NavyFOAM.
