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.

Application: Scanning Technology Enables CFD at Reynard

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.

Events: Turbulence and Heat Transfer Modeling Seminar
Posted Mon November 25, 2002 @09:12AM
Print version Email story Tweet story
ANSYS CFX Predicting heat transfer using eddy viscosity turbulence models often produces poor results mainly due to the low Reynolds number near-wall treatment and not so much from the underlying turbulence model. Studies by Wolfgang Vieser, Thomas Esch and Florian Menter of CFX have shown that using the CFX-5 SST turbulence model, in combination with an optimal wall treatment, does provide highly accurate results for a wide variety of heat transfer test cases. Dr. Florian Menter will be in Florida on December 11 presenting a seminar on this topic.

Topic: Turbulence and Heat Transfer Modeling in CFX-5

Date: December 11, 2002 during the PowerGen International Conference

Time: 9 am - noon

Location: Orlando, Florida

Visit the seminar website for more information and to register.

Print version Email story Tweet story
Grid Generation Pointwise, Inc. has released version 14.04 of their flagship CFD pre-processing program Gridgen.

The latest release of Gridgen enhances functionality with new CFD solver interfaces (Splitflow and PHOENICS) and new graphics features (Zoom to Screen Extents and single increment rotations). Additionally, the elliptic PDE solver for structured grids is now up to 5 times faster and Glyph, Gridgen’s Tcl-based scripting language introduced in V14, continues to expand in scope to cover more and more of Gridgen’s functionality.

To learn more about the new features in Gridgen V14, visit the Pointwise website at

Events: CFD-based Aircraft Drag Prediction and Reduction
Posted Thu November 21, 2002 @10:59AM

News VKI Lecture Series Announcement:
3 - 7 February 2003, von Karman Institute, Belgium

Ever since the very beginning of aerodynamic flight, the accurate prediction of aerodynamic drag has been a major challenge in the aircraft design process. During the past 20 years, Computational Fluid Dynamics (CFD) has come to play an increasingly important role in this respect, but significant advances in CFD modelling capabilities are still needed. Future improvements in performance of transport aircraft (notably fuel efficiency and hence direct operating costs), will largely depend on reducing aerodynamic drag. This will be achieved by design optimization and technologies such as laminar flow control, areas in which CFD will play a vital role.

The objective of this Lecture Series is therefore to present the state-of-the-art and current research directions in CFD-based drag prediction. The course is aimed at applied aerodynamicists and CFD researchers as well as aircraft designers.
