摘要：Plate separators are widely used for oil-water separation in the petrochemical industry. The spreading process of oil droplets at the solid surface is the key to understanding the oil-water separation mechanism in the plate separator. This study uses VOF method to capture oil-water phase interface change and sets up a two-dimensional model of oil droplets spreading on solid surface in water. The influences of droplet diameter, oil-water interfacial tension and viscosity are studied. The numerical simulation results show that the maximum spreading length of oil droplets increases with the increase of droplet size and interfacial tension. The average spreading speed of oil droplets decreases with the increase of oil droplet size, and increases with the increase of surface tension. The maximum spreading length and average spreading speed of oil droplets decrease with the increase of the dynamic viscosity of the oil droplets. ? Published under licence by IOP Publishing Ltd.
