Abstract/Summary An integral approach has been developed to model propagation of sound through the combustion zone for practical combustors based on the Green’s function technique. Sample calculations done for typical gas turbine combustors indicate that models based on jump conditions across the flame can be quite inaccurate in predicting the acoustic mode shapes (pressure and velocity). There appears to be a strong dependency on the mean temperature profile inside the combustion zone on the final mode shapes of the acoustic quantities. The technique presented herein can be readily adapted to different models for heat release and various temperature profiles.
