Flow and Transport Modeling
Principal Investigators: Mojdeh Delshad and Gary A. Pope
Abstract
The objective of this research is to develop and apply a three-dimensional, multiphase,
multicomponent model capable of simulating the fate and transport of nonaqueous liquids
(NAPLS) in the saturated and unsaturated zones of confined and unconfined aquifers. The
model is capable of simulating multiple solids and fluid phases under realistic aquifer
conditions and transformation of both organic and microbiological species. Some of the
specific objectives of this research are:
Incorporate appropriate physical, chemical and biological process models important to describe the fate and transport of contaminants in nonfractured and fractured porous media, such as, non equilibrium interphase mass transfer, sorption, cation exchange, decay processes, microbiological and geochemical reactions, hysteretic capillary pressure and relative permeability.
Some of the current applications of the model are: NAPL spill and migration in both saturated and unsaturated zones; partitioning interwell tracer test in both saturated and unsaturated zones of aquifers; remediation using surfactant/cosolvent/polymer; remediation using surfactant/foam; remediation using cosolvents; bioremediation; and geochemical reactions e.g. heavy metals, radionuclides
Please see the UTCHEM page for more information about the model.
