Abstract
A multicomponent evaporation and dissolution model was applied to study the
dynamics of the mass transfer of dispersed oil in shallow waters. This model, in
Lagrangian form, was coupled with the Princeton Ocean Circulation model
(POM) for simulating oil droplet dispersion in an oceanic environment. The oil
dispersion was modeled for a standard sea-mount shallow water environment.
The most abundant petroleum hydrocarbons in the hydrocarbon-enriched of oil
plum larger than C1-C5 were benzene, toluene, ethylbenzene, and total xylenes.
Therefore, the oil surrogate, which consists of these components, is studied. The
liquid–liquid equilibrium and vapor–liquid equilibrium equations are solved for
evaluating the droplet life time. A rapid mixing model is used by reason of the
shorter internal mass diffusion time scale in comparison to the droplet life time.
Four different droplet sizes, 1.5, 1, 0.5, and 0.1mm, are considered in this study.
The droplet with a diameter of 1mm has a shorter life time in this specific
environment.
Keywords: multicomponent oil droplet dispersion, evaporation, dissolution,
ocean circulation model, Rapid mixing model.
1 Introduction
Multicomponent liquid droplet size history during evaporation and dissolution
influences the dynamic behavior of the droplets, whereas the variation of the
composition determines the distribution of the fuel compounds within the
environment, and also the droplet life time. The fundamental understanding of
