文摘

The effects of both gap ratio and oblique angle on VIV response are investigated. The validity of the IP is examined for a near-wall cylinder under oblique flows. The critical normal reduced velocities for the onset of VIV are obtained. Different vortex shedding modes at the onset of VIV are observed.
