STUDY OF THE VORTEX-SHEDDING INFLUENCE ON THE DRAG COEFFICIENT AND THE SHAPEOF IMMERSED FLEXIBLE CYLINDERS

Long flexible immersed cylinders are frequently encountered in the form of towing cables, risers, pipes, etc. In the past it has been common to assume a drag coefficient of 1.2, as for a rigid cylinder, when investigating the shape assumed by such cylinders, the stresses in them and their dynamic behaviour; these predictions can, however, be in error. The authors suggest that this is due to the assumption of an erroneous value for the drag coefficient, and report on experimental work undertaken to investigate the effects of vortex shedding and induced vibrations on the drag of cylinders.
