| dc.description.abstract | An experimental study is presented on the application of Large Eddy BreakUp (LEBU) on a flat plate as a sourcetargeting device to perturb the wall pressure fluctuations of a turbulent boundary layer. When interacting with a LEBU wake, the wall pressure spectra can establish a self-similar behaviour against s′, which is a normalised separation distance between the LEBU’s trailing edge and the targeted location for aeroacoustics noise source mitigation. It is found that s′ >3is neededto achieve an overall reduction in the wall pressure fluctuations. The fundamental mechanism by which the LEBUcanreducethewall pressure fluctuation is investigated by studying the spatio-temporal evolution of turbulent spots. When the emanated LEBU wake is interacted with the outer part of turbulent spot, the shielding effect can always inhibit the turbulent fluids ejection from the spot’s leading edge. However, incursion of the high momentum f luids wall-sweeping event at the spot’s trailing edge can only be effectively prevented when s′ > 3. | en_US |
