Target Audience: 一般
Note (General): Characteristic features of small disturbances originating from a point source on a yawed cylinder were experimentally investigated in order to decide the critical Reynolds number near the attachment line. Various frequencies were examined by hotwire measurements. The results showed that the disturbances propagate downstream in wedge-like regions and the cross-flow instability is dominant for all the frequencies examined here in comparison with the streamline-curvature instability. For lower frequency disturbances the neutral points were clearly observed in contrast to the higher ones. A critical Reynolds number for off attachment line was obtained. The value is about 7% lower than the well known critical Reynolds number Rc=583 for attachment-line instability.
