摘要：
Experimental results show how vortex-induced vibration (VIV) amplitudes of flexible cylinders can be reduced up to a 90% by covering less than half of the length of the cylinder with splitter plates elastically mounted to the surface of the cylinder. The VIV amplitude reduction takes place along with drag coefficient reductions of up to a 50% for the reduced velocities investigated. (C) 2014 Elsevier Ltd. All rights reserved.
