Figure 3.5 Flow visualization of vortex shedding at several 

 spanwise (z) locations along a stationary and vibrating flexible 

 cable, at a Reynolds number of Re = 570, from Ramberg and 

 Griffin 0. (a) Stationary, z = 0.25 L. (b) Stationary, z = 0. 

 (c) Vibrating (node of the vibration pattern), z = 0.25 L and V, 

 = 5.2. (d) Vibrating (antinode), z = 0, K, = 5.2 and 2?/D = 

 0.3. The wavelength of the vibration pattern is denoted by L.
