### 6.3.4. Oil Evaporation/Combustion

The oil combustion model uses the particle transport model to track evaporating oil droplets, which are modeled in a very similar way to the liquid evaporation model, and uses the eddy dissipation model for the combustion of the volatile gases in the gas phase.

- Liquid Evaporation Model

#### 6.3.4.1. Light Oil Modification

The light oil modification bases the physical parameters used in the Reynolds number, the Nusselt number, and the Sherwood number on the gas assumed to be in the boundary layer of the droplet. This, in turn, depends upon the Antoine equation (that is, if the drop is boiling, the gas in the boundary layer is all volatiles). In the other extreme, the gas in the boundary layer consists entirely of the local gas mixture.
