  • Alexandre Tartakovsky selected as a recipient of PECASE award.
    • July 2009
      Project co-PI Alexandre Tartakovsky was named as a recipient of the Presidential Early Career Awards for Scientists and Engineers, the highest honor bestowed by the United States government on young professionals in the early stages of their independent research careers. Alexandre is one of twelve DOE researchers to be selected, and will receive his award in the Fall at a White House ceremony.
  • Scheibe selected as 2010 Darcy Lecturer
    • May 2009
      Project PI Tim Scheibe has been invited by the National Ground Water Research and Educational Foundation to serve as the 2010 Henry Darcy Distinguished Lecturer. He will give 30-50 invited lectures at universities and other research/educational institutions across the US and internationally during the year. Both of his offered lecture topics will include selected results of research conducted under this project. Prospective host institutions can submit a lecture request form at the NGWA website.

  • American Geophysical Union (AGU) Outstanding Student Paper Award
    • February 2009
      UC San Diego doctoral candidate Ilenia Battiato was cited for her poster presentation at the 2008 Fall AGU meeting describing her work under this SciDAC project entitled "Mixing-induced precipitation phenomena: Range of applicability of macroscopic equations." Her poster was presented in December 2008 at the AGU Fall Meeting. Her formal citation appeared in EOS Trans. AGU 90(18):159, 2009.
Pore-scale simulation image
Zoomed-in view of a 3D visualization of pore-scale fluid flow computed using the parallel Smoothed Particle Hydrodynamics code developed under this project. Solid grains are represented as shaded gray quasi-spheres. Transparent surfaces indicate regions of high fluid flow velocity. Traces of individual fluid particles are also shown, colored according to their velocity (with bright green being the fastest particles). Visualization created by Kwan-Liu Ma and colleagues at the Institute for Ultra-Scale Visualization, University of California at Davis.

Computational Hybrid Integration of Physical Processes across Scales (CHIPPS)

Hybrid Numerical Methods for Multiscale Simulations of Subsurface Biogeochemical Processes: In this SciDAC Science Application, we are developing an integrated multiscale modeling framework with the capability of directly linking different process models at continuum, pore, and sub-pore scales. These codes will be modified and/or developed using advanced high-performance component architectures and efficient parallel solvers, and will be integrated into a component-based workflow environment to facilitate seamless integration of codes operating at multiple scales with different physical, biological, and chemical conceptualizations appropriate to the needs of specific simulation problems.
