TMVOC

TMVOC is a numerical simulator for three-phase non-isothermal flow of water, soil gas, and a multicomponent mixture of volatile organic chemicals (VOCs) in multidimensional heterogeneous porous media. It is an extension of the TOUGH2 general-purpose simulation program developed at the Lawrence Berkeley National Laboratory. TMVOC is designed for applications to contamination problems that involve hydrocarbon fuel or organic solvent spills in saturated and unsaturated zones. It can model contaminant behavior under "natural" environmental conditions, as well as for engineered systems, such as soil vapor extraction, groundwater pumping, or steam-assisted source remediation. TMVOC is upwards compatible with T2VOC and can be initialized from T2VOC-style initial conditions.

The main enhancements in TMVOC relative to T2VOC are as follows:

• a multicomponent mixture of volatile organic chemicals can be modeled;
• any and all combinations of the three phases water - oil - gas are treated;
• several non-condensible gases may be present;
• diffusion is treated in all phases in a manner that is fully coupled with phase partitioning.
