A Numerical Model for Petroleum Hydrocarbons Transported by Sediment Laden Flows in Open Channels

Presented in this paper was a numerical model for the Petroleum hydrocarbons transported in sediment laden flows. The model was developed base on the basic equations of the two-fluid model for sediment laden flows so that the fate and transport of either dissolved or particulate phase of PHs can be simulated without introducing partition coefficient. More important was that by invoking the two-fluid model the model longer need the assumption that the particulate phase of PHs was under the same convection and diffusion effect as dissolved phase. Verifications by flume experiments were also presented in this paper. Comparisons between simulations and observations indicated that the model presented in this paper has a fairly good accuracy so far as the flume data were considered.
