Experimental investigation on straight-fin helical strakes with varying geometric parameters for vortex-induced vibration suppression

This paper experimentally investigates a simplified straight-fin helical strake for vortex-induced vibration (VIV) suppression of cylindrical structures, aiming to mitigate manufacturing difficulties and drag penalties of conventional strakes. Tests cover Re = 2×10 4 –1×10 5 and...
