摘要: The flow and transport of organic compounds in variably saturated porous media is investigated using a compositional simulator. simulator incorporates number numerical options to maximize computational efficiency accuracy. effect field scale heterogeneities on the movement demonstrated. influence infiltrating wetting fronts gas phase volatile shown be significant. long-term fate subsurface spill three-component dense liquid simulated. Three-dimensional simulations soil vacuum extraction demonstrate difficulty removing dissolved from zone with this process.
