Categorytrue1Zhang, HaitianFurther Development of the ROSI Beamforming Method for the Investigation of Turbomachinery Investigated at an Angle114BeBeC-2020-D131, BeBeC-2020-D13112020The ROtating Source Identifier (ROSI) beamforming algorithm is a method designed
for localizing rotating noise sources in a uniform flow utilizing out-of-flow measurements
of the acoustic pressure field. It has been developed for sources moving along a circular
path, such as turbomachinery blades. The original ROSI method takes the average of the
measured acoustic signal over a long time segment in order to reconstruct the noise sources.
By doing so, it does not take into consideration certain features of the noise sources, such
as differences between the trailing edge and the leading edge noise sources of the given
blades. A further development of the method is presented herein, which separates the
pressure signal of one revolution of a given noise source into multiple segments. This
method will be referred to as the segmented ROSI method. Using this method, the
beamforming maps can provide a better understanding as to the differences between the
noise sources as a function of angular position. The goal of this further development is to
improve the capability of the method in identifying the position-dependent differences
between the noise sources that are rotating around an axis. The new segmented ROSI
method is presented through a series of example cases, comparing it to the original ROSI
algorithm. Though the publication only presents the theory behind the method under
development and a few basic validation cases, the results are promising regarding the
applicability of the method to other more complex tasks upon fine tuning the method and
the associated code.truefalse2020truetruetruetruetruefalseGOLD2022-04-05truehttp://real.mtak.hu/11484610101111111000101010000FolyóiratcikkJournal Article241KönyvrészletChapter in Book250KönyvBook230Egyéb konferenciaközleményConference paper310Egyéb konferenciakötetConference proceedings320Oltalmi formákProtection forms260DisszertációThesis280EgyébMiscellaneous290AlkotásAchievement220Kutatási adatResearch data330FolyóiratcikkJournal Article24000KönyvrészletChapter in Book25000KönyvBook23000Egyéb konferenciaközleményConference paper31000Egyéb konferenciakötetConference proceedings32000Oltalmi formákProtection forms26000DisszertációThesis28000EgyébMiscellaneous29000AlkotásAchievement22000Kutatási adatResearch data33000202201010false10041387falsefalsefalse2020-12-26T10:27:10.131+0000Áramlástan Tanszék (BME / GPK)33130truetrue10002English
