Steady State Spreading of Oil Spilled on the Surface of water Streaming

Abstract

Steady state spread of oil slick formed when the oil is continuously poured on the surface of uniform water stream is dealt with. Theory is developed by means of the twolayers model which takes into account the lateral spread of oil slick whose velocity is assumed proportional to the advancing velocity of the density front. Governing equaions of the average thickness, average velocity and the width of oil slick are derived. Calculations of width of oil slick is compared with experimental data.
