Abstract:

This paper presents measurements of the simultaneous flame position and flow velocity in a high pressure, liquid fueled combustor. Liquid fuels injected in swirling flows are commonly used in gas turbines, but data collection and analysis pose a challenge in the two-phase, reacting flow field, particularly when operating at high pressure. Measurements in a liquid fueled, swirl combustor were performed using simultaneous, high speed stereo-PIV, OH-PLIF and fuel-PLIF. The OH and fuel fluorescence were separated, and regions of liquid fuel, OH and liquid fuel+OH were identified during data reduction. The measurements were taken at elevated pressures to visualize the gaseous and liquid flow field, heat release region and fuel spray distribution. This paper extends work in a prior paper by analyzing the sensitivity of the physical locations of these regimes to the processing approach.
