Experiments were performed at the Air Force Research Laboratory's Propulsion Directorate (AFRL/RZ) in Research Cell 22 (RC22). Twelve cases from the experiment were computationally analyzed and each case varied in either engine operating condition and/or combustor configuration. Initial computations were performed on all twelve cases to establish a baseline computational approach. Computations were performed on one of the cases to test sensitivity to turbulent Schmidt number, reaction rate, and grid ...
A technique to develop flight-like inflow conditions for direct-connect testing has been extended in the current work. This technique utilizes an expansion/contraction section upstream of the engine isolator in a direct-connect test facility to create shock waves consistent with those generated in flight. The current work improves upon the earlier work by better matching the inlet shock structures, the average conditions at the engine throat, and boundary layer properties. RANS ...
