摘要: There is disclosed a system comprising a substantially cylindrical element, at least one strake element about a circumference of the cylindrical element, wherein at least one of the strake elements are closed and comprise a thickness measured in a direction along a longitudinal axis of the cylindrical element less than two times an outside diameter of the cylindrical element, and wherein the strake elements operate to reduce the vibration of the cylindrical element when the cylindrical element is subjected to a fluid current.
