Application by Bob Cramblitt

Combustion Research and Flow Technology, better known as CRAFT Tech, says it likes to swim in data.

Not just any data, of course. CRAFT Tech immerses itself in terabyte-sized datasets used to simulate complex fluid dynamic and combustive problems. To swim in these waters requires large-scale, parallel architecture computers running specialized CFD codes and the most advanced visualization software.

A recently completed project called HiFAST (High Frequency Acoustic Suppression Technology) showcased CRAFT Tech’s ability to take full advantage of CFD visualizations at every phase of weapons system development. The project, conducted for the Air Force Research Laboratory’s Air Vehicles Directorate (AFRL/VAAI), culminated in a successful flight test of a device that controls internal weapons bay airflow and acoustics.

Perfect Flight At Last

News New flow simulation software developed at the Army High-Performance Computing Research Center (AHPCRC) incorporates automatic mesh generation technology directly in the flow solver allowing the mesh to adapt to changing conditions and geometries during the simulation.

In the Desktop Engineering article Perfect Flight At Last, Dr. Andrew Johnson of the AHPCRC describes how moving mesh CFD techniques offer new ways to model complex fluid-structure interactions such as a hummingbird’s hovering flight.

In early 2005, we began working with the new parallel programming language Unified Parallel C (UPC) with the goal of building new types of codes that would be difficult or impossible to implement using MPI. We quickly recognized that UPC would allow us to create a new type of CFD code that supported much more complex simulations, including dynamic mesh methods.

Events: Turbulence Workshop Scheduled
Posted Wed May 10, 2006 @09:23AM
Print version Email story Tweet story
News Turbulence modelling is a key element in Computational Fluid Dynamics (CFD). Despite this, a single mathematical model that covers all kind of turbulent flows has not yet been derived. Instead, an engineer must choose from a wide range of different turbulence models, each having it´s advantages and disadvantages. This is, however, not really surprising since the objective of turbulence modelling is to approximate an extremely complicated phenomenon.

Fluent Sweden AB will host a Turbulence Workshop intended for CFD engineers who face turbulent flows in their daily routine and are looking for efficient ways of ensuring reliable results. The workshop will be held June 7-9, 2006 in Gothenburg.
