Figure 2.1 The cross flow displacement amplitude 2YI D for a circular cylinder plotted against the 

 reduced velocity V^ = ^/fn^- Data points denoted by ( + ,•) were measured in a wind tunnel us- 

 ing a cylinder with a natural frequency /„ = 52 Hz and diameter D = 6.1 mm (4). Data points 

 denoted by (B) were measured in water using a cylinder with /„ = 2.2 Hz (air), 2.0 Hz (water) 

 and D = 25 mm (5).
