ARGONNE, Ill. (Jan. 17, 2008) – Twenty research projects have been
awarded more than 111 million hours of computing time at the Argonne
Leadership Computing Facility (ALCF) at Argonne National Laboratory.
William Tang of Princeton University and the Princeton Plasma Physics Laboratory was awarded 2 million hours to gain a better understanding of turbulence as a primary mechanism by which particles and energy diffuse across the confining magnetic field in toroidal fusion systems. Results from these studies may have direct relevance to the future performance of the international burning plasma experiment called ITER.
Thierry Poinsot of the European Centre for Research and Advanced
Training in Scientific Computation was awarded 4 million hours for a
first-time application of a new simulation method – called Large Eddy
Simulation – to the computation of the unsteady reacting flow within a
complete helicopter turbine chamber.
William George of the National Institute of Standards and Technology
was awarded 750,000 hours to study the flow of dense suspensions and
related colloidal systems composed of rigid bodies, with and without
interparticle interactions, having a wide range of size and shape, and
under a variety of flow conditions, such as shear and around obstacles.
Paul Fischer of Argonne was awarded 14 million hours to carry out
first-principles-based simulation and analysis of reactor core cooling,
which will provide insight to design improvements leading to increased
safety and economy of advanced reactors.
Giulia Galli of the University of California-Davis (UCD) was awarded 6
million hours to conduct quantum simulations to investigate how water
interacts with the surfaces of various materials and to study how the
properties of liquid water change when confined in very small spaces.
A Pratt & Whitney team led by Peter Bradley was awarded more than
1.3 million hours to develop improved aircraft engine combustor
simulations to enable reduced emissions and improved operability.
Kelly Anderson of Proctor and Gamble was awarded 4 million hours to
investigate the molecular mechanisms of surfactant-assisted bubble
