Abstract

A mathematical model of oleic spot propagation based on the laws of conservation of mass and total energy of the system is constructed. Compact solutions of this model are presented both for machine oil stains of limited area and for unlimited spills of crude oil. Experiments have been carried out to study the dynamics of spreading of a compact spot of reference engine oil and crude oil under various physical conditions. Comparison of experimental and theoretical results showed their good agreement for all dynamic modes of the process under study.
