Abstract

The purpose of this research was to operate a bluff body flame holder with the objective of stabilizing a flame at elevated pressures over a range of equivalence ratios. The ability to have a ground-based test rig capable of maintaining stable flames at high pressures and temperatures is critical in understanding flames present in modern jet engines and gas turbine technologies. The facility was reconfigured multiple times and the resultant flame was imaged within the optical test section. A converging nozzle was utilized to choke the flow and vary the operating pressures up to 5 atm. By regulating mass flow rates of both the fuel and air, the target range of equivalence ratios was achieved. Jet fuel was successfully ignited on the bluff body and a flame was maintained in the recirculation zone. Visualization of flames during the flights of any aircraft is limited due to material and weight requirements, therefore, performing these studies in ground- based facilities is required. Further analysis was performed to characterize C2* and CH* radicals in fuel lean and rich flames.
