Simulation of Mass Transport Using the FracTran98 Module of FracSys2000
By David M. Diodato
Abstract
FracTran98 is the transport module of FracSys2000, a new suite of simulation
tools for modeling flow and transport in multiphase or single phase, fractured
or unfractured porous media. FracTran98 simulates transport by advection alone
or by coupled advection-dispersion in a one- or two-phase flow field. An optional
immobile "free" phase may be present. Linear kinetic partitioning between the
mobile phases and the immobile free and solid phases is supported. An example
of toluene contamination in the unsaturated zone shows that sluggish kinetics
can substantially extend the time required for remediation in porous media.
FracSys2000 also includes a flow module (FracFlow96), and a visualization module
(FracVis98).
