The chemically reacting flow in the mixing and secondary zone of the improved RQL combustor sector of the DLR has been numerically investigated. The combustion model is adapted to meet experimental conditions and proves to underpredict temperature fluctuations. The pressure dependence of the NOx emission index for the quench and lean zone of the combustor can be described with an exponential factor of 0.66. Although the level of agreement between measured and calculated results is not consistently good, the code can be used to study the effect of various operating conditions as well as the effect of geometrical changes on the flow and the emissions.
