ABSTRACT: Study of non-stationary phenomena in turbulent combusting flows requires spatial measurements of a set of parameters at kHz rates. Ideally these parameters would include the velocity , temperature, and a relevant species concentration. In response to this need, ORBITEC and the University of Wisconsin-Madison propose to develop a technique to measure velocity, temperature, and OH concentration simultaneously at repetition rates greater than 50 kHz. The technique will seed the flow with phosphor particles and quantify velocity via PIV and the temperature via luminescence. PLIF will obtain the OH concentration. The Phase I work will demonstrate the three measurements at rates up to 50 kHz rates and will design a pulse-burst laser system for development during Phase II. The Phase II work will develop the refined PIV+T+OH technique incorporating the pulse-burst laser system and will test the technique in practical combusting flows. The result will be a highly useful diagnostic for the combustion community. BENEFIT: The technique developed on this STTR program will be useful in acquiring spatially and temporally resolved data in combusting flows. This type of data is useful to researchers in numerous government and civilian entities. The Air Force at the DoD are the initial customers; subsequent commercialization will extend to NASA and the automotive and aerospace industries.
