Business: CFX Wins Multi-Year Order from Siemens
Posted Tue December 03, 2002 @04:48PM
Print version Email story Tweet story
ANSYS CFX The CFX division of AEA Technology, a leading supplier of computational fluid dynamics (CFD) software and services to the power generation, mechanical and chemical process industries, announces a global multi-year commitment by Siemens Power Generation to use CFX for design analysis by engineering teams in both Germany and the United States. CFX software and expertise is used by Siemens to optimize design and improve efficiency in all parts of their steam and gas turbines.

The CFX suite of integrated software provides Siemens with the ability to simulate and visualize flows inside a turbine, enabling a better understanding of the issues involved in creating superior designs. Siemens Power Generation, Mülheim an der Ruhr, Germany, has used CFX software to develop design rules for highly-efficient steam turbine blades that were subsequently employed to design the world’s most efficient steam turbine to date, with 48.5 percent gross efficiency, for the VEAG power plant in Boxberg, Germany.

Print version Email story Tweet story
AVL AVL is proud to open the industry's first online meshing and grid generation service for CFD (Computational Fluid Dynamics) and FEA (Finite element Analysis) applications.

Grid generation for complex geometries can be a time consuming process, where experience is needed and the right tools are essential. eFAME provides an internet solution which is based on the powerful automatic mesh generation tool FAME by AVL.

Mesh generation for complex geometries has never been easier. Just submit a surface description of your computational domain in the commonly used STL-file format and the eFAME mesh generation engine will provide you, within a short time, with comprehensive information on the automatically generated mesh. Then you decide if the mesh is of value to you and if you would like to obtain the corresponding mesh file in the universal file format at the specified fee.

Project Boosts Performance of Rotor-Stator Flow Calculations

ANSYS CFX By Martin Kuntz and Florian Menter, CFX

During the last three and a half years, CFX has actively participated, as CFD software provider, in the European HPNURSA (High Performance Numerical Unsteady Rotor Stator Analysis) research project. The project, which started in 1998, recently closed with a workshop at the 21st IAHR meeting held in Lausanne, Switzerland in September 2002. Within the project, CFX worked closely with VA TECH HYDRO, as industrial end-user, and the Universities of Lausanne (EPFL) and Lyon (ECL) as academic partners.

The complexity of unsteady rotor-stator flows makes them highly computer intensive, as they require a transient simulation with sufficiently small time steps to resolve the unsteady features of the flow. Furthermore, the full 360-degree machine must generally be modelled, leading to multiple blades per row in the simulation. These demands increase CPU and memory requirements by at least an order of magnitude compared to steady-state simulations. If such computations are to be tractable for industrial users, the use of advanced computer and programming technologies is essential. These issues have been addressed by the HPNURSA project, providing improvements to the unsteady time integration formulation, enhancements of the transient rotor-stator interface and the optimization of the parallel performance of CFX-TASCflow and CFX-5.

ANSYS FLUENT For the past three years, the biggest sport in the world, Formula 1 Motor Racing, has been dominated by the Italian Scuderia Ferrari Racing Team. To be successful in Formula 1 demands a mastery of leading edge technology in order to produce a fast reliable car.

A major factor in the design of such cars is their aerodynamic efficiency. Computational Fluid Dynamics (CFD) plays a crucial part in Formula 1 aerodynamic design processes at Ferrari. The Ferrari team uses the FLUENT CFD code for all their CFD simulations, Fluent being the fastest growing CFD supplier to the worldwide Automotive Industry.

To celebrate this winning partnership, Fluent and Ferrari have printed a limited edition set of posters depicting a virtual Ferrari Formula 1 race car in classic CFD pressure contour format, with a real F1 race car just behind it on a Grand Prix race track. These A2 size posters are being offered free from Fluent Inc. to the first 350 people to request them.

Application: Scanning Technology Enables CFD at Reynard
Posted Mon November 25, 2002 @05:37PM
Print version Email story Tweet story
Application The differences between motor racing on two wheels and four go far deeper than just arithmetic. In Formula 1, for instance, races are routinely won and lost in the pits; on motorbikes, the archaic practice of overtaking is still regularly reported. It is behind the scenes, however – away from the cameras – that the real differences between the two sports really emerge.

At any particular race, a Formula 1 car represents the current state of the art, a snapshot in an ongoing multimillion-pound research and development project. Teams recognize the importance of the most advanced design, simulation and testing techniques – and spend, spend, spend accordingly. The teams that race high performance bikes are every bit as keen to succeed but here the emphasis tends to be more on fine tuning and trimming rather than turning out machines that evolve steadily (sometimes dramatically) throughout a season.

Part of this is down to motorcycle racing’s rules and regulations: in some races every entrant must ride an identical bike, so room for design innovation is distinctly limited. And money is certainly an issue. The fact that individuals still race on a reasonably competitive basis with their more highly funded rivals is a reflection of the fact that cash is spread somewhat thinner than in Formula 1 racing.
