Flow control in flow–structure interaction

Influences of the helical strake cross-section shape on vortex-induced vibrations suppression for a long flexible cylinder

“…VIV may cause serious fatigue damageon the structures in offshore engineering. Much research work has been done on this typical fluid-structure interaction phenomenon throughout centuries, both numerically and experimentally, toward the understanding of the dynamic response features of VIV (Naudascher, 1987;Sarpkaya, 2004;Gabbai and Benaroya, 2005;Williamson and Govardhan, 2008;Wu et al, 2012b;Fan et al, 2015) and the VIV suppression (Zdravkovich, 1981;Bearman and Owen, 1998;Galvao et al, 2008;Assi et al, 2009;Wu et al, 2012a;Huera-Huarte, 2014;Gao et al, 2015aGao et al, , 2015bGao et al, , 2016.…”

“…Compared with active control, passive control is easier to implement, but it usually requires an initial parametric study for a successful control result. Different passive control methods for suppressing VIV have been studied by many researchers [16][17][18][19][20].…”

Experimental investigation of flow-induced vibration on isolated and tandem circular cylinders fitted with strakes

“…Special attention has been paid to passive control because, among the three different groups, passive control is the easiest to implement in experiments, but it usually requires an initial parametric study for a successful control result. Different passive control methods to suppress vortex shedding and VIV have been studied by Bearman and Owen (1998), Galvao et al (2008), Assi et al (2009), and reviewed by Zdravkovich (1981). Among the various geometrical forms of devices for passive suppression, helical strakes are some of the most common in both air and water flows, as can be seen in chimneys and offshore structures, such as risers and spars.…”
