Developed by Dr. Andre Unger and his team at the University of Waterloo, CompFlow is a state-of-the-art numerical modeling tool that solves 3D multiphase (water/gas/oil) or (water/DNAPL/dissolved contaminants) compositional flow and transport problems occurring in complex porous soil as well as discretely fractured rock. CompFlow employs parallel computing to simulate flow and transport processes on a standard PC or in the Cloud environment. This modeling tool has been used to evaluate the feasibility of implementing enhanced bioremediation technologies, individually or in various combinations, to address groundwater contamination arising from hydrocarbon source zones.

Comprehensive Simulation Capabilities:

  • Fully/variably saturated flow and contaminant transport modeling
  • Multiphase flow, multicomponent contaminant transport modeling with biodegradation
  • Density-dependent groundwater flow and solute transport
  • Groundwater flow and heat transport, which allows performance of subsurface thermal energy storage/recovery and geothermal simulations
  • Fractured porous media simulation with discrete fractures and dual porosity conceptualization
  • State-of-the-art bioreaction module allowing for simultaneous aerobic/anaerobic biodegradation
  • 3D simulations that can evaluate the feasibility of implementing, individually or in various combinations, the following technologies:
    • Electrical resistance heating (ERH)
    • Soil vapor extraction (SVE)
    • Subsurface carbon sequestration and storage (SCS)
    • Continuous/pulsed air sparging (AS)
    • Aquifer thermal energy storage (ATES)

CompFlow Application Examples:

Example1 : Simulation of DNAPL Plume Migration in Aquifer System with Fractured Bedrock
Example 2: Simulation of subsurface CO2 Sequestration and Storage (SCS)
Example 3: Simulation of Aquifer Thermal Energy Storage (ATES)
