Subsurface Flow and Transport

EMSL users can employ subsurface flow and transport capabilities to study chemical reactions in heterogeneous natural materials with an emphasis on soil and subsurface systems. EMSL's approach to subsurface flow and transport studies is holistic, integrating flow cells, analytical tools, tomographic imaging, and predictive modeling capabilities to study subsurface phenomena. Topics of interest include:

A variety of flow cells is available to EMSL users, including: column, batch, radial, wedge, and rectangular. Micromodels with desired pore structures can be fabricated from various substrates to study flow and reactive processes at the pore scale. Flow cells are used in coordination with high-precision, high-sensitivity analytical tools to generate data about sample characteristics by detecting the presence of carbon, trace metals, ions, nonvolatile compounds, thermally labile chemicals, and more. Pore structures and other heterogeneities in natural materials can be imaged using EMSL's X-ray computed tomography instrument. EMSL users also can design experiments using the predictive subsurface flow and transport simulator, STOMP (Subsurface Transport Over Multiple Phases). Data derived from experiments using EMSL's subsurface flow and transport capabilities are used to further refine STOMP, continually increasing its precision.
