摘要

基于系统的质量守恒定律和总能量守恒定律，提出了油类浮油扩散的理论模型。在此基础上，导出了描述各时间点扩散过程的近似方程。给出了有限面积机油泄漏和原油无限泄漏情况下该方程的紧凑解。通过实验研究了参考机油和原油在不同物理条件下致密浮油的扩散动力学。实验结果与理论结果的比较表明，实验结果与理论结果吻合较好。

On the Radial Spread of Petroleum Products on the Surface of Water

A theoretical model of the spreading of an oleine slick based on the laws of conservation of mass and total energy of the system is presented. Based on this model, an approximate equation describing the spreading process at each time point is derived. Compact solutions of this equation are presented both for engine-oil slicks of limited area and for unlimited spills of crude oil. Experiments are conducted to study the dynamics of the spreading of a compact slick of reference engine oil and crude oil under various physical conditions. Comparison of the experimental and theoretical results show their good agreement for all dynamic modes of the process under study.
