Navier-Stokes Solution Worth 1 Million Dollars
Posted Mon July 22, 2002 @10:09PM
Print version Email story Tweet story
News The Clay Mathematics Institute of Cambridge, Massachusetts (CMI) has named seven “Millennium Prize Problems.” The Scientific Advisory Board of CMI selected these problems, focusing on important classic questions that have resisted solution over the years. The Board of Directors of CMI have designated a $7 million prize fund for the solution to these problems, with $1 million allocated to each.

Among the seven problems is a call for the solution to the Navier-Stokes Equations. The challenge is to make substantial progress toward a mathematical theory which will unlock the secrets hidden in the Navier-Stokes equations.

In order to be awarded the prize, the solution must prove one of the four following statements:

  1. Existence and smoothness of Navier–Stokes solutions on R3
  2. Existence and smoothness of Navier–Stokes solutions in R3/Z3
  3. Breakdown of Navier–Stokes solutions on R3
  4. Breakdown of Navier–Stokes Solutions on R3/Z3

Since we don ’t even know whether these solutions exist our understanding is at a very primitive level. Standard methods from PDE appear inadequate to settle the problem. Instead we probably need some deep new ideas.

Features: CFD Speeds US Navy Aircraft Modifications

Application Warren H. Davis, Ph.D., Aero CFD Principal Engineer for Northrop Grumman, leads a team responding to continual updates, additions, and enhancements to the U.S. Navy electronics surveillance workhorse, the E-2C Hawkeye. The Hawkeye provided stellar success in Afghanistan missions earlier this year.

Dr. Davis is one of the people who answers the “will it fly right” question when confronted with next generation modifications. He helps assure that any modifications to aero/propulsion capabilities, airframe additions including antennas, and other changes maintain and enhance performance.

Dr. Davis and his team gauge adaptations on the computer, using two remarkable programs (among other tools): Gridgen and Overflow. Gridgen is Pointwise Inc.’s grid generation and pre-processing CFD enabling bridge connecting computer aided design (CAD) software and CFD solvers such as Overflow, Fluent, STAR-CD, and CFX. The program generates hexahedral, tetrahedral, and hybrid (prisms and pyramids) meshes, reads geometry from CAD systems, and includes meshing tools and direct solver interfaces. Overflow is a Navier-Stokes flow solver that uses single block grids or Chimera overset (structured) grid systems. Chimera overset grids are body-fitted hexahedral grids around each component. They can overlap each other instead of requiring exact point-to-point interface matching like traditional structured grids. This makes the engineer’s grid generation task faster and easier while maintaining accuracy.

News Coupled 1D/3D STAR-CD Training Course
Nuremberg, Germany
September 23, 2002

The CD adapco Group offers all European users the opportunity of understanding of how to set-up and effectively run three dimensional STAR-CD analyses coupled to a one dimensional engine simulation code, GT-POWER.

The course is aimed at giving the STAR-CD user an understanding of how to set-up and effectively run three dimensional STAR-CD analyses coupled to a one dimensional engine simulation code. The course will use GT-POWER as the engine simulation code. For some components, a more stable and realistic STAR-CD analysis is obtained by allowing the unsteady STAR-CD analysis results to interact with (influence) the domain boundary conditions. In addition to instruction, the course will provide the STAR-CD user with hands-on experience through use of a worked example. The course also offers the user the opportunity to interact with an experienced engineer who has run several coupled analyses.

Application The engineers at Spalding know there is more to the game of golf than skill and concentration. For instance, there is a lot of science behind the design of the golf balls. Designing them to fly higher and go farther is a tricky task. Scientists at Spalding Sports Worldwide are now using CFdesign fluid flow simulation software from Blue Ridge Numerics to better determine which new designs will go the distance.

News The CD adapco Group invites you to see a live web based demo of STAR-Works...

STARWorks, which uses the STAR-CD solver, is an easy-to-use tool designed for engineers/designers who require a quick and cost effective way to perform simple fluid flow and heat transfer simulations within an environment they are familar with - CAD!

...and down the road, when you need a more powerful CFD tool, learn how STAR-Works gives you an easy migration to the full advanced features of STAR-CD.

Upcoming show dates: 30 minute duration.

August 13th & 27th: 10.00 am (US Eastern time)
September 10th & 24th: 10.00 am (US Eastern time)
