Turbulent combustion in burners causes low frequency broadband combustion noise. Before the noise from such burners can be reduced, the generating mechanisms must be understood.
Noise generation by a simple can-type burner has been investigated. Several parameters are varied to study their effect on the far-field noise spectrum. The noise characteristics of the burner observed in this work are generally similar to those updated in the literature.
A combustion noise data base is developed for use with an analytical model in isolating the acoustic source structure within the burner. The source distribution with frequency subject to an assumed spacial distribution is recovered from far-field acoustic pressure measurements used in conjunction with the analytical model for a limited number of the cases investigated experimentally. / Master of Science
