FORCES ON A SUBMERGED BODY WITH AND WITHOUT FINS UNDER A TRAIN OF REGULAR WAVES,

Abstract

Under a regular beam sea, the forces and moments acting on a circular cylinder with and without a pair of fins were measured experimentally. The test cylinder had a length-to-diameter ratio of 6.17. Five configurations were tested, one without fins and four with variations in fin size and fin location. The presence of a pair of fins reduced suction forces considerably. The largest reduction was effected by fins one-half the cylinder radius in height, positioned at an angle of 60 degrees from the horizontal plane passing through the cylinder axis. Conformal transformation and the Blasius theorem were used in a theoretical analysis, the results of which agree fairly well with experimental findings. (Author)
