Combustor Design Model Evaluation.
Abstract
The objective of the program was to evaluate, develop and validate more accurate computer-based analytical models for combustor flows to be used in combustor design. The joint velocity-scalar probability density function (pdf) method, which overcomes several key deficiencies of conventional turbulent combustion models and offers greater accuracy for combustor design calculations, is the focus of the program. Significant progress has been made under this program towards the development of the pdf method as a combustor design tool. Several new models and algorithms used in the pdf method have been developed. The method and the models have been validated in detail for a variety of flows, including swirling, recirculating and reacting flows, involving the essential features of gas turbine combustor flows. The validation was performed using available benchmark quality data, as well as data from specifically designed experiments which were performed at Wright Laboratory. A baseline pdf based combustor design system has been developed.
