FLUENT 6.0 is released, Fluent Inc.'s Flagship CFD software offers virtual flow prototyping for the HVAC industry

Fluent : 17 December, 2001  (New Product)
Fluent Inc., announces the release of FLUENT 6.0. A new set of features in this version specifically address the needs of HVAC engineers using CFD to build and test virtual prototypes of their designs for fans, pumps, compressors, indoor air quality, duct and environmental flows, heat exchangers, appliances, and many other applications.
Fluent Inc., announces the release of FLUENT 6.0. A new set of features in this version specifically address the needs of HVAC engineers using CFD to build and test virtual prototypes of their designs for fans, pumps, compressors, indoor air quality, duct and environmental flows, heat exchangers, appliances, and many other applications.

FLUENT 6.0 is a major update of the world's most commonly used CFD software. The software's popularity has been built on its ease-of-use, modeling versatility, and flexible unstructured meshing technology, which enables engineers to quickly build virtual prototypes which accurately reflect reality. Advances applying to the HVAC (heating, ventilation and air conditioning) industry largely address important applications such as rotating machinery, internal and external airflow, heat transfer, and phase change.

Fast Fan and Pump Curves
Several new features in this version are specifically focused on the modeling of rotating equipment, and can be applied to fans, pumps, and compressor design. First, rotating machinery-specific panels let the user easily calculate key integral quantities like torque and efficiency, create plots on meridional, pitchwise, and spanwise cuts, and automatically display plots of circumferentially-averaged flow parameters. Second, improvements in Fluent's mixing plane model and implementation of non-reflecting boundary conditions provide improved accuracy and robustness for multistage machines. Finally, a specialized rotating machinery model set-up tool, G/Turbo, is also now available from Fluent for performing fast, automated model set-up.

Thermal Comfort and Pollutant Dispersion
With FLUENT 6.0, engineers can predict flows within interior spaces such as rooms, offices, cleanrooms, and laboratories. The presence of screens, vents, fans, and diffusers can be included in the analysis. This sophisticated capability is being used today for indoor air quality and thermal comfort studies, as well as for predicting pollutant dispersion in safety analyses.

Environmental Flows
Improvements in Fluent 6.0's turbulence models and unsteady flow algorithms will favorably impact such environmental flow applications as emissions from smoke stacks and power plant cooling towers, and wind load calculations on buildings and other structures.

Heat Transfer and Phase Change
With a full suite of models to address all forms of heat transfer, FLUENT 6.0 can perform complex, multimode thermal analyses for applications such as heat exchangers, natural convection heating and cooling, and solar energy. New advanced capabilities for handling phase change prediction are ideal for application to HVAC engineering problems involving melting or freezing (e.g. ice formation).

Multiphase Flows
Fluent 6.0 provides the HVAC industry with best-in-class capabilities for multiphase flows. Users can now activate sophisticated models for applications involving general gas-liquid flows, bubble and droplet modeling, free surface flows, cavitation, particle-laden flows and more. Applications benefiting from this technology include refrigeration systems, chillers, consumer appliances, water heaters, and air handling units.

Speed Multiplies with Parallel Processing
FLUENT's near-linear scaling during parallel processing has been head and shoulders above other general purpose CFD software, and this position is further advanced with FLUENT 6.0, where dynamic load balancing and other advanced features enable users to easily distribute their FLUENT problems across a network of UNIX, Linux, or NT processors for faster turnaround of results.

Usability Enhancements
FLUENT 6.0 offers a new set of options for postprocessing and visualization, such as automatic generation of animations. Results can be output in VRML format, which enables the user to send three-dimensional images of results across the Web for remote viewing, where the receiver can change views, zoom in/out, and rotate the image.
