The acoustic transfer characteristics of combustion systems are of particular
importance for a stability analysis of combustion instabilities.
Especially a description of the burner and flame are required.
In this work, transfer characteristics of an acoustic area change, an atmospheric swirl burner and -flame were computed by means of flow simulation and system identification.
The results were compared with experimental data.
A comprehensive process for the computation of such transfer chracteristics was developed.
Also, the energy transfer from a swirl flame to the acoustic wave was investigated.
