|Title:||A Two-phase Flow Model For Oil Spills In River Sections|
|Abstract:||An in-house two-dimensional two-phase model to describe oil spill in river sections was presented. A two-dimensional geometry was adopted since the oil flows on the water. Due to the irregular geometry of rivers banks, the momentum and mass equations were written in curvilinear coordinates. An orthogonal grid method was developed to represent the river surface, as the finite volume method requires orthogonal grids. A Eulerian-Eulerian approach was used for the mass and momentum balances, written in curvilinear coordinates. A zero-order turbulence model was used to account for turbulence. The model can be used to predict miscible effluent dispersion in a river section. A software was developed from the model and results for both miscible effluent dispersion and oil spill were presented. This is an abstract of a paper presented at the AIChE Annual Meeting (Salt Lake City, UT 11/4-9/2007).|
