Mechanisms of Exhaust Pollutants and Plume Formation in Continuous Combustion.
Abstract
The development of combustors that are both fuel efficient and fuel flexible requires spatially resolved measurements of velocity, temperature, and concentration in complex flows representative of both premixed and non-premixed systems. Such data are needed to provide the physical insight necessary to understand the basic processes of turbulent mixing and transport, and support the evolution of modeling. The goals of the AFOSR program was to develop laboratory model combustors and experimental methodology suitable for the acquisition of the desired information. The objectives of the program were to establish and evaluate laboratory model combustors for both premixed and non-premixed fuel air injection suitable for studies of the complex flows; to acquire spatially resolved flowfield data using state-of-the-art diagnostics for the purposes of model verification and providing insight into the transport of mass, momentum, and energy in complex flows; and to conduct supplementary studies to support the development of methodologies required for measurements in complex flows. Four combustion modules were considered: the Opposed Jet Combustor (OJC) for premixed injection and, for non-premixed injection, the Centerbody Combustor (CBC), the Centerbody Combustor with swirl, and the Dilute Swirl Combustor (DSC). An evaluation of combustor performance and compatability with a list of criteria for laboratory complex flow combustors established the DSC as a viable configuration for non-premixed, complex flow combustors studies in which swirl was a major aerodynamic feature.
