Acoustic measurements within combustion chambers are expensive due to high thermal loads applied on the measurement devices at operating conditions. As a more feasible substitute, probe microphones can be used to lead acoustic waves from combustion chambers to externally mounted microphones. Since these probe microphones are purged by nitrogen at atmospheric temperature, high thermal loads are avoided. However, the acoustic signal measured by the probe microphone is altered compared to the… CONTINUE READING
