Characterization of various soils and their flow properties. Our approach combines the following tools and techniques:
  • X-Ray Computed Microtomography (CMT);
  • microscale flow simulation (using the Lattice-Boltzmann Method);
  • parallel commodity-based clusters and graphics cards (GPUs) computaions;
  • high-performance data analysis and visualization tools.

Micrometeorite studies. CMT at BNL is used to analyze micrometeorites for the presence and location of high attenuation cores and low attenuation pores (described in [1]). Shown is a micrometeorite (279 microns diameter) with its outer surface (blue) made transparent. The red mass is a metal nugget; the yellow regions represent metal oxides.
