High Reynolds Number Wave Force Investigation in a Wave Flume.

Abstract

A 12.75-inch diameter vertical cylinder was subjected to large laboratory waves with Keulegan-Carpenter number up to 17 at the local force transducer (20 at the still water surface) and Reynolds number up to 270,000(320,000 at the still water surface). Local force, local pressures, total force, and the elements for determining the overturning moments were measured. The purpose was to produce a high quality data set in the wave regime where both the velocity and the acceleration-dependent components of the wave forces are important. It was found that the forces were more acceleration-dependent than originally anticipated. The local forces were predicted quite well with the two-term Morison equation using the kinematics from the measurements, the linear, and the stream function wave theories. The best predictions used the measured kinematics. Keywords: Wave forces; Experiments; Large scale; Morison equations; High Reynolds; Cylinders; In-line forces; Transverse forces.
