Modeling Multiscale-Multiphase-Multicomponent Subsurface Reactive Flows using Advanced Computing (Peter Lichtner, Los Alamos National Laboratory, PI).

There are two groundwater science applications currently funded by SciDAC. Although these have distinct objectives, the two projects offer strong opportunities for collaboration and sharing of information. We have frequent interactions with Dr. Lichtner, including direct collaboration that resulted in a published paper (Tartakovsky et al., Water Resources Research 44: W06S04, doi:10.1029/2006WR005725, 2008). Two PNNL staff on Dr. Lichtner's project (Glenn Hammond and Steve Yabusaki) provide a strong avenue for continued communication and collaboration between the two groundwater projects.

Office of Biological and Environmental Research (BER) Project Collaborations:

The 3D parallel SPH code developed under this SciDAC project is being adapted for application to BER-funded research under the PNNL Science Focus Area: Role of Microenvironments and Transition Zones in Subsurface Reactive Contaminant Transport. This work will use the SPH code to simulate intragranular dissolution and diffusion-controlled transport of uranium in Hanford Site sediments based on molecular-scale research of Chongxuan Liu and others (Liu et al., Water Resources Research, 42: W12420, doi:10.1029/2006WR005031, 2006). This work has potential applications at the Hanford Integrated Field Challenge (IFC) site at the 300 Area (pictured below).

Centers for Enabling Technologies:

We have established collaborations with several of the SciDAC Centers and Institutes that are developing technologies of high value to our project:
