Acoustic Methods for Measuring Thickness of Oil on Water

📖 The Scoop

The knowledge of the thickness of oil slicks floating on water is a primary requirement to establishing the amount of oil and to deciding on appropriate spill countermeasures. This study focuses on acoustic methods for measuring oil thickness on water using surface acoustic waves or frequency dependence of the amplitude of reflected acoustic energy. The study consisted of a theoretical investigation to assess the feasibility of using surface acoustic waves and an initial exploratory experimental program to generate and detect Rayleigh waves in oil. A limited scope experimental study was undertaken to determine the initial feasibility of the technique and to establish whether a more comprehensive experimental program was justified.
