Contributions to the Experimental Characterization of Fan Noise Radiation
Identifying the modal content of an acoustic source propagating from a ducted fan based on measurements of the radiated pressure requires the determination of transfer functions between the modes exiting the conduit and the microphone array. This thesis focuses on the generation and validation of transfer functions between acoustic sources in the conduit and a far-field geodesic microphone array. An iterative Bayesian inverse approach is employed, along with numerical simulations, to produce the functions. These functions are validated by performing mode reconstruction using data garnered by an in-duct microphone array. Possible applications of this thesis include employing the modal breakdowns to optimize duct intakes and evaluating engines via field testing without the need for invasive measurements.
