...-flow direction, which is the simplest configuration of cylindrical structures. One can refer to the review by Bearman (1984), Parkinson (1989), Blevins (1990), Sarpkaya (2004) and Williamson and Govardhan (2004). However, unlike single rigid cylinder, it has not been researched so extensively for two...

... by the capture of the vortex shedding frequency by the oscillation frequency over a range of cylinder oscillation amplitudes. This phenomenon is called lock-in. Meneghini, Saltara and Bearman (1997) investigated square, saw-tooth and parabolic wave forms of cylinder transverse oscillations, and found that only...

... generation are also square or rectangular. But so far the existing research on small cylinders has been concentrated on the care of a circular cylinder, with very few studies are related to the square cylinder(Bearman 1980, 1984, Deroich 1992). Consequently the research on wave current forces acting...
