ANALYSIS OF COMBUSTION GENERATED NOISE

Studies of the various aspects of combustion generated noise are presented. These include: an extension of Lighthill's acoustic analogy to combustion generated noise and using the theory to derive expressions for the sound power output and characteristic frequency; a study of sound propagation in ducts in the presence of combustion; calculation of flow fields in combustors; and a procedure for calculating the spectrum of combustion generated noise. The predictions of the theories presented here are shown to be in good agreement with experiment.
