Application: A Landmark in Simulation
Posted Tue October 28, 2003 @05:31PM
Print version Email story Tweet story
Application by Nick Waterson,
Mott Macdonald, UK

Mott Macdonald is an international engineering and management consultancy based in the United Kingdom and operating world wide in the fields of construction, transportation, energy, water resources, the environment and education.

The Simulation Group within Mott Macdonald has been using CFX-4 and CFX-5 from ANSYS CFX for more than 12 years to solve a wide variety of problems relating principally to fire safety, wind engineering and power generation.

The Maitreya Project International is planning to build one of the largest statues of the Buddha in the world. The statue, with a height of 152m and a design life of 1000 years, is to be located in northern India. Mott Macdonald has been acting as consultant for a number of aspects of the design as well as the project management. The unusual nature and size of the structure mean that a number of advanced analysis techniques, including computational fluid dynamics, are required to overcome the many design challenges. During the preliminary design phase, one key issue to be addressed was the effect of extreme wind loads on the structure. It was decided to use a CFD approach for the initial determination of these loads, to be backed up by wind-tunnel testing and further CFD studies later in the project.

Application A SoftInWay application story details the steady state coupled fluid and solid thermal analysis of a steam turbine secondary flow path.

Prediction of steam turbine rotor and stator thermal state is a complex problem that usually is divided into a set of interdependent problems related to steam flow, heat transfer and thermo-mechanical modeling. Some of most important modeling issues can be identified as follows:

  • Turbine flow path heat transfer boundary conditions;
  • Heat transfer boundary conditions related to the secondary part;
  • Secondary steam flow including the flow in disk/diaphragm cavities and seals;
  • Windage losses;
  • Turbine rotor and stator thermal steady analysis;
  • Seals radial/axial clearance optimization.
The predicted thermal state shows a significant influence of secondary steam bleed flow on the temperature distribution of the rotor and stator.

In the Minority - Women Using CFD
Posted Thu October 23, 2003 @04:00PM
Print version Email story Tweet story
News According to 2002 data from the U.S. Bureau of Labor Statistics, women represent just over 10 percent of the engineers in the US. A Boeing story discusses the role women have had at Boeing, including design and analysis.

From the first aircraft of a new company to the worldwide production and support of thousands of jetliners in service today, women have contributed significantly to the success of The Boeing Company.

[Peg] Curtin's kite project led her to Notre Dame, where she earned bachelors and masters degrees in aerospace engineering, and then to Boeing. She now works with wind tunnels that blast high-speed air over models of new airplane configurations. Her computer runs computational fluid dynamics programs that predict how different shapes will perform.
