![]() In collaboration with Professor Julia Dobrosotskaya at CWRU, we are actively working on continuing to improve our advanced optical flow velocimetry (OFV) methods and apply them to new problems in a project funded by NSF. We are performing experiments using the HOPLITE and high speed imaging, as well as partnering with the Naval Surface Warfare Center to simulate the flow phenomena using high-fidelity computational tools.Īdvanced Optical Flow Velocimetry (OFV) methods We are particularly interested in the changes which occur when the projectile impacts the water at supersonic speeds relative to the speed of sound in water, which is about 1.4 km/s. In a project funded by the Office of Naval Research Young Investigator Program (YIP), we are researching the effects of projectiles entering water at hypersonic speeds. The HOPLITE was funded by a Defense University Research Instrumentation Program (DURIP) grant from the Air Force Office of Scientific Research, and is currently under construction by Physics Applications, Inc.įor a full list of Professor Schmidt’s publications, including those prior to his position at Case Western Reserve University, please see his Google Scholar page.Ĭurrent projects Risk Evaluation for Aerosol-Generating Procedures The bore diameter is 18 mm, and it will be capable of launching models at speeds up to 4 km/s. The hypervelocity projectile light gas gun ( HOPLITE) is a two-stage light gas gun that will be used to launch projectiles to hypersonic speeds for aerodynamics research. HOPLITE 2-stage light gas gun (Coming soon!) These windows allow schlieren-based techniques such as BOS to be performed in the TRIREME tunnel without the optical distortions that would typically occur in water tunnels due to lower optical quality glass or acrylic windows. ![]() The side walls of the test section can be replaced with blocks which have inserts for high-quality optical glass with λ/10 flatness. The laboratory is outfitted with state-of-the-art equipment for high speed (up to 1 MHz) imaging and stereoscopic 1 kHz PIV. ![]() It features a 30 cm x 30 cm x 1 m test section and a maximum velocity of 1 m/s. The Turbulence Research, Imaging, high-Resolution Experimental Methods, and Education ( TRIREME) Water Tunnel is a water tunnel specifically designed to provide an ideal testbed for novel, flow visualization-based experimental techniques and for fundamental studies of turbulence.
