Key Features
- Temporal and spatial variations in the source
(residual dense or light non-aqueous liquids), and its
composition, and volatilization fluxes to the air
phase updated continuously.
Oil ( gas mass transfer
simulated as a kinetic process
- Multiple wells, and spatial variation in
extraction/injection rates simulated.
- Simulation of heterogeneous and/or anisotropic
porous media.
- Easy to use Mesh Editor: create 3-D finite element
mesh, define soil zones, and assign boundary
conditions -- all within the Processor.
- Convection, dispersion, diffusion, first order
biodegradation simulated.
- Computationally efficient matrix solution by
conjugate gradient method with
preconditioning
Input
- Mesh discretization data
- Initial conditions: water pressures (import/enter
monitoring wells water level data).
- Initial conditions for transport
- Species’ gas concentration
- Soil hydraulic properties
- van Genuchten parameters, porosity
- Hydraulic conductivity
- Longitudinal and transverse dispersivities, and
species’ diffusion, first order decay, solubility, oil
( gas mass transfer, and Henry coefficients.
- Boundary conditions for gas flow:
- Specified gas pressures, and/or flux/source/sink
boundaries
- Boundary conditions for transport:
- Specified species’ concentrations, and/or
flux/source/sink boundaries
- Spatial distribution of contaminants
