| Description | VENT2D is a 2D finite difference, multi-compound vapor transport and phase partitioning model. The program solves the vapor-phase advective and diffusive fluxes of up to 60 compounds in a 35 x 35 grid. The chemical compounds can partition into the vapor, dissolved, adsorbed and a nonaqueous phase liquid (NAPL). The 2-D grid can be given any distribution of permeability and initial contaminant concentrations. The model continuously tracks the water and NAPL saturations to update the soil-gas permeability, pressure and flow fields. The 2D grid also allows spatially-variable leakage of clean air from the third dimension into the model domain. It is suited to modeling soil vapor extraction (SVE) as a means of remediating contaminated soil. |
