REDUCED VELOCITY, V^ = V/f^D 



Figure 2.24 Measured peak cross flow displacement amplitude 

 Yl D plotted as a function of the reduced velocity V,. A slender, 

 fully submerged and cantilevered circular cylinder was employed 

 as the model (LID = 52. D =_12.7 mm (0.5 in))_for experi- 

 ments conducted in uniform (/3 = 0) and shear (/3 = 0.01 to 

 0.015) flows of water. The cylinder was a 1:168 scale model of a 

 full-scale marine pile with the same specific gravity (SG = 1.5), 

 from experiments reported by Fischer, Jones and King (40) and 

 King (16). In the case of the shear flow V is the maximum 

 value in the nonuniform incident velocity profile. The figure 

 was provided by Dr. Warren Jones of the Shell Development 

 Company.
