Paper presented at the The Twelfth ISOPE Pacific/Asia Offshore Mechanics Symposium, October 4–7, 2016
Paper Number: ISOPE-P-16-137
... Abstract The effect of yaw angle ( α ) on hydrodynamic forces of a yawed square cylinder oscillating in still water is studied experimentally. The independent principle (IP) was examined by evaluating the hydrodynamic coefficients that derived from the measured in-line and lift forces using a...

Paper presented at the The Ninth ISOPE Pacific/Asia Offshore Mechanics Symposium, November 14–17, 2010
Paper Number: ISOPE-P-10-054
... ABSTRACT: The hydrodynamic force acting on a fin oscillating beneath a free surface is investigated. To safely utilize floating structures under severe environmental conditions in the sea, the motion of the floating body and the mooring forces acting on the body should be reduced. To decrease...

... forward speed. Therefore, it can be safely said that the phenomena occur only when hydrodynamic forces are dominant comparing with hydrostatic forces like buoyant forces. Then, the phenomena are generally referred to as dynamic instabilities (Blount & Codega, 1992). Although the phenomena are dynamic...
