Abstract
A method for computational aeroacoustics, in which the acoustic field is split from the flow field, is applied to the flow around automobile rear-view mirror placed on a large solid plane. In this study, the pressure fluctuations on the solid plane are investigated with a high-pass filter at 500Hz. The calculated results show that the flow fluctuations are dominantly generated by the stay of the mirror body, whereas the acoustic fluctuations are affected by the mirror body. The fluctuation levels of the acoustics exceed those of the flow at almost equal distance of the mirror length from the object except the wake region.
