abstract

This paper discusses a new type of vortex-induced vibration (VIV) suppression devices, the blade Henning device, named after one of the primary inventors, Dean Henning. It consists of four blades, 90-degree apart, on a circular shaped sleeve. Tests of these devices on a flexible cylinder in uniform flows have been conducted. The results indicate that the amount of suppression required with this type of apparatus to effectively mitigate VIV is significantly reduced.
