Forcing Pulsations by Means of a Siren for Gas Turbine Applications (Journal Publication 2020)

An article summarizing 20 years of experience about CBOne's pulsation Technology and focusing on the very latest developments has been published in the International Journal of Turbomachinery for Propulsion and Power. To this point, we wish to thank the Board of the EVI-GTI Conference for their recommendation for journal publication.

CBOne developed a special actuator, able to generate with precision airflow modulations over the 0-6000 Hz range, with amplitudes achieving up to 150 dB SPL. The article describes into details:

  • The siren technology
  • The generation of a precision airflow modulation, for dynamic sensor calibration purpose
  • The drive of flow dynamics, for laboratory applications
  • The drive of thermoacoustics, for gas turbine applications
