Abstract
The KIVA-II code was modified to allow calculation of the flowfields in a staged gas turbine combustor including the air-blast fuel nozzle. The results illustrate the complicated flowfields present in staged combustors. In particular, the thermal protection requirements of the quick-quench mixer used in this study may be similar to those of the rich-burn combustor, despite the presence of the cool dilution jet. Variation of the mass flow split between the fuel nozzle air passages has a significant effect on the velocity and temperature profiles. In addition, the slanted dilution slots form a counter-rotating flowfield. From the results obtained to date, it appears that the modified KIVA-II code can be used to study the effects of various staged combustor designs and operating conditions. © 1995 American Institute of Aeronautics and Astronautics, Inc., All rights reserved.
