Abstract:

A mathematical model was developed to describe the forces acting on an oil slick under saline ice in the presence of a water current. The model was verified through a set of laboratory experiments conducted in a recirculating flume located in an 'ice room' facility. The results were also compared to similar experiments conducted under freshwater ice. It was found that oil slicks moving under saline ice experience an increase in frictional resistance due to the small scale roughness of the ice undersurface. The friction force can be approximated by assuming 'no-slip' at the oil-ice interface and a linear velocity distribution in the slick.
