ItemCross fire simulation rig(Georgia Institute of Technology, 2013-03) Zinn, Ben T. ; Lubarsky, EugeneThe primary purpose of the project was to investigate the threshold for flame propagation between two combustors of crossfire rig designed to simulate conditions in a GE gas turbine engine.

ItemA novel augmentor that does not use flame holders to stabilize the combustion process(Georgia Institute of Technology, 2012-06) Zinn, Ben T. ; Lubarsky, Eugene ; Neumeier, Yedidia ; Williams, AimeeThis report describes the process of determining auto-ignition delay of the liquid Jet-A aviation fuel injected in a cross flow of vitiated air. Auto-ignition delays were measured by processing of the time-averaged chemiluminescence images for a range of temperatures from 898-1028K, vitiated oxygen percentages from 9.3% to 12.2%, velocities from 80 – 140 m/s and global Jet-A to, vitiated-air mixture equivalence ratios from φ=0.3 to φ=1.5. It was found that ignition delay increases exponentially from one to ten milliseconds with inverse temperature variation and are more scattered at lower temperatures. The data obtained in this study reveals delay times much shorter than those measured in most of other studies, but with same character of dependence upon the temperature of the flow.
