Oil Spreading on the Snow Ice Surface

(By Sergey Ovsienko, Sergey Zatsepa, Alexander Ivchenko; INSROP Working Paper No. 6 – 1995, I.5.6)

This paper describes oil spreading on ice or snow surface. Description of the physical basis, mathematical formalization and original numerical technique for oil spreading simulation is represented. Shallow-water-like equations for viscous liquid are used for oil spreading on the ice or snow surface. Oil penetration into oil or snow is reduced to a one-dimensional process equation. The boundary of oiled area is considered to be unknown, and is determined in the process of solution. The particles-in-cell technique based on quasi-Eulerian adaptive grids is used. The numerical solution results are compared with known analytical solutions. The question of the model tuning is discussed.
