内容記述 | Flow noise associated with separated flow of a flat plate with large attack angles was studied experimentally to obtain its acoustic characteristics and to understand its generation mechanism. The acoustic features show that the separated flow noise could be attributed to the wall-pressure fluctuations on the plate surface, being of acoustic dipole sources. The time derivatives of fluctuating wall-surface pressure are highly correlated with the associated acoustic pressure. The noise source strength is proportional to the mean-square time-derivative of fluctuating surface pressure and its correlation area, being proportional to the sixth power of the oncoming flow velocity and distributed uniformly over the plate surfaces. The associated acoustic intensity is well predicted with these noise-source strength distributions. | |||||
