Abstract:

Model studies of oil containment barriers and herding devices were conducted in an open channel of six foot width and three and one-half foot depth. Currents up to four feet per second were used with three different oils. Incipient failure of the barriers occurred for values of the densimetric Froude number of about unity. Trajectories of the oil drops at incipient failure are given. Oil herding devices were tested at various angles to the current. This performance in regard to loss rates was superior to that of the barriers, and improved as the angle between current and herder was decreased. Multiple barriers and barriers with nets were also tested. A vortex oil recovery device was conceived and tested, which showed only very small loss rates at all speeds tested. Its rate of recovery of a slick increased with current speed.
