ABSTRACT: ORBITEC will develop a new diagnostic to acquire simultaneous planes of velocity and temperature data at very high repetition rates. This diagnostic relies on a novel pulse burst laser system, a phosphor thermometry technique, and the mature PIV method. The work plan will involve developing and testing the laser, refining the integrated technique, and demonstrating it in a supersonic flow. The result will be a new diagnostic that will be very useful to the combustion community for generating temporally and spatially resolved data in reacting flow and for validating CFD models. The resulting products will have a promising market in both military and civilian applications. BENEFIT: This STTR program will produce several viable products: The PIV+T diagnostic, the pulse burst laser, the phosphor particles, and testing services. Because the PIV+T technique is designed for turbulent reacting flows, it will have applications in air-breathing engines, IC engines, and rocket engines. The markets include many branches of the military and many civilian companies.
