As our nation's technologies deployed in space become more sophisticated,
they also become more vulnerable to phenomena which occur in the near-Earth
space environment. As a consequence, a national goal has been set
to produce a physics-based model that would provide accurate predictions
of phenomena, enabling technology operators to protect their assets
from space storms. |

Research performed by the Ground Vehicle Aerodynamics Group at Old
Dominion University analyses heavy ground vehicle aerodynamics. Their
study is a benchmark case, resulting in a database containing both
experimental and computational results. These results will lead to
modification devices that minimise drag force and increase fuel efficiency.
This will also lessen environmental pollution and improve stability
and vehicle control. |

Analytical and Computational Engineering, Inc., develops tools for
simulating explosions. Their models predict or reconstruct the most
likely blast scenario surrounding an event. Engineers use these results
to calculate the risk from an industrial explosion or terrorist attack.
The results are then used to design and retrofit buildings and other
facilities. |

Principal Scientist Derek Goring is with the Coastal Hydrodynamics
Group on the South Island of New sealand. His research seeks to understand
how sea levels vary around the coast. This plot shows how at any time
there is a high tide somewhere on the New sealand coast. This means
there is a two meter difference in sea level across a relatively small
distance which causes a strong tidal flow. This phenomena is very
unusual and occurs only one other place ? Iceland. |

The Mississippi River Gulf Outlet System was built in 1963 as a
shortcut for ocean-going ships bound for New Orleans. It has resulted
in tremendous environmental damage, such as salt water intrusion and
wetland loss, as well as weather and flooding threats. For Lake Pontchartrain
this intrusion led to the endangerment of fresh water marshes that
surround the lake. Ioannis Georgiou develops models that serve to
investigate the flow exchange and dynamics of the impeding salt water
as well as the impact the salt water has on Lake Pontchartrain's ecosystem. |

Dr. Warren Davis was a design consultant to the AmericaOne syndicate,
a contender for the America's Cup 2000 in Auckland, Ns. He was involved
with the underwater design including the hull, keel, bulb, wing and
rudder appendages. The design team's goal was improve the boat's speed
by reducing hull and appendage drag. Weather and wave conditions vary
for different sailing courses, so this boat was optimised for the
course in New sealand. |

M. L. Raghavan researches and models the biomechanics of aneurysm
disease. By visualising the stress distribution, surgeons can get
a better idea of the aneurysm's rupture risk, the most susceptible
region, whether or not to perform the surgery, and then plan their
surgical intervention accordingly. Since surgery is risky, surgeons
need to balance the risk of rupture with the risk of surgery before
deciding to perform the AAA resection. |

Third Wave Systems, Inc., develops finite-element based software
for simulating metal cutting. Their applications are used by aerospace
and automotive engineers to optimise speed, minimise waste and reduce
costs associated with metal cutting. While the simulation is running,
or after it has been completed, users view results with Tecplot. |

Preston Martin specialises in experimental rotorcraft aerodynamics.
This plot investigates the flow physics associated with the vortex
wake of a hovering helicopter rotor. The single rotor blade is shown,
along with the motor and counterweight. The rotor is thrusting upwards
and the flow passes down through the X-Y plane. Trailing from the
tip of the blade is a vortex filament, as shown by the red line. In
contrast to a fixed-wing aircraft, the vortices trailing from a hovering
helicopter remain in close proximity to the aircraft lifting surfaces. |

David Glase's focus is on fundamental research and numerical modeling
of turbulence in a variety of disciplines. This includes combustion,
aeroacoustics, and multiphase flows. This simulation was run on the
NCSA SGI Origin2000 Supercomputer. The code ran in parallel on 16
processors, using a total of nearly 6 GB of RAM and about 10,000 hours
of CPU time. |

TSI, Inc., developed a Tecplot add-on to post-process the vector
field data collected by their Particle Image Velocimetry (PIV) system.
Pioneered by TSI, PIV is one of the most prominent noninvasive diagnostic
techniques. PIV measures the instantaneous velocity field and the
associated flow properties. A pulsed laser light sheet illuminates
the flow field of interest and two images, separated by a very short
interval in time, are captured. Cross-correlating the images provides
the velocity vector fields and associated statistical properties.
TSI?s PowerView PIV systems use Tecplot as part of the INSIGHT image
capture, analysis and display package. |

A fishery biologist with the US Geological Survey's Columbia River
Research Laboratory, Derrek Faber is working to preserve salmon runs
through various dams in the Pacific Northwest. This plot represents
water velocity in a juvenile salmon bypass mounted to the face of
Bonneville Dam. His goal is to gain a better understanding of the
flow conditions around juvenile salmon bypasses. Ultimately, the information
will help in collecting salmon and passing them through dams without
having to travel through turbines. |
