文摘
FIV experiments for a triangle prism are performed in a water channel. An amplitude variation coefficient is proposed to describe FIV stationarity. The prism goes into the transition branch from VIV to galloping when 7.8 < Ur < 10.4. The prism can extract hydraulic energy in an infinite range of flow velocities.
