- W2100363366 abstract "mitigated. This paper investigates the opportunity for increasing the attenuation of downstream propagating tonal noise using inter-liner scattering. This is achieved by changing the axial sequencing of seven dierent cylindrical segments that were originally optimised to attenuate the broadband source noise. The fully scattered field for all possible segment permutations is computed in order to establish the optimum segment order and elucidate the principles behind the exploitation of interliner scattering. A simple reordering of the absorbers is shown to provide a significant range in overall attenuation and this range increases with the length of the absorbers. The results are analysed by considering the changes in the modal distribution of downstream propagating energy along the duct in order to explain why some liner sequences are more eective than others. The best sequences present the most eective absorbers with a radial mode energy distribution that can be more readily attenuated. This means that all the scattering events that occur upstream of a liner can be significant and the performance of a liner will be based on the configuration of the system, not just localised eects. In general, axial scattering has a detrimental eect on overall liner performance when a large number of modes are cut-on. The importance of the source characteristics are highlighted by changing the number of fan stators to reduce the number of radial modes cut-on. This allows inter-liner scattering to be more eectively exploited. In summary, the analyses suggest that the ordering of absorbers should be a key part of any multi-segmented liner optimisation." @default.
