Abstract
A new unique reduced order heat release model is proposed for development in this SBIR. The proposed reduced order heat release model is derived based on the prevailing local flow conditions and it expresses the complex relationship between the fluctuating heat release and the fluctuating local variables. The reduced order heat release model will be developed independent of the pressure-acoustic model used to model screech acoustics and as such it can be integrated with any acoustics model. The reduced oreder heat release model will be based on finite-rate chemical kinetics which can be either global, reduced, or detailed. In addition, limited experimental work will be carried out to provide data on the fluctuating heat release and pressure behind a bluff-body type flame holder. The data will be used to validate the reduced order heat release model.
