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.
