AN ANALISYS OF THE SPREAD OF CONTINUOUSLY SPILLED OIL ON WATER CURRENT

In this paper, the spread of continuously spilled oil on a uniform flow are dealt with experimentally and theoretically. The laboratory experiments were performed in a circulating water channel. The oil was continuously pored onto the surface of uniform water current from the small outlet. The plane view of the spreading oil slick was observed. Mathematical model is developed on the basis of two-layer model and kinematic wave theory. Thus the governing equation of the front velocity of oil slick is derived. Calculations of the advance of the slicks show similar tendency to experimental data.
