Evidence and physical mechanism for vortex-induced vibration of a bluff body without an afterbody
W Chen, Y Li - Physics of Fluids, 2023 - pubs.aip.org
Afterbody—the portion of the body downstream of shear layer separation points—was
believed to be essential for the vortex-induced vibration (VIV) of a bluff body. A recent study …
