The AeroGust Project - Aeroelastic Gust Modelling
Posted Tue July 18, 2017 @06:26AM
 Print version Email story Tweet story
Application A key element in the design of an aircraft is to make sure it can cope with the stresses arising from the impact of strong winds on the plane’s structure. Calculating the way the aircraft reacts to gusts and turbulences is essential knowledge before a plane can be built.

Currently most of the data concerning gusts is gathered during expensive wind tunnel experiments and rather late in the design process, when design options have already been narrowed down a lot.

Application Using ANSYS engineering simulation technology to design and optimize its high-performance yacht, Emirates Team New Zealand defeated Oracle Team USA to win the 35th America’s Cup, 7-1.

The need for speed is critical on the water and small changes can make the difference between first and last place.

3D Inverse Design of Centrifugal Compressor Impellers with Splitter Blades
Posted Fri June 23, 2017 @12:53PM
 Print version Email story Tweet story
Application ADT has published a white paper on improved centrifugal compressor design through CFD analysis.

In the design of centrifugal compressor impellers with splitter blades it is quite common to use the same blade shapes on the full and splitter blades with the splitters placed at the mid-pitch location. However, recent results using conventional design methodology have indicated that by moving the pitch wise location of the leading edge of the splitter it is possible to improve splitter performance.

 Print version Email story Tweet story
Application Siemens has posted an informative discussion of whether CFD should be performed at model scale or full scale. The answer, of course, is that "it depends".

Putting scale in perspective: CFD for design exploration in the marine industry looks into the differences in CFD simulation at model and full scale and the assumptions involved.

Design High Performance Centrifugal Compressor Vaned Diffusers
Posted Wed June 07, 2017 @05:36PM
 Print version Email story Tweet story
Application The design of the vaned diffuser of a centrifugal compressor is still based on a considerable amount of empiricism in its design methodology. Parameters such as area ratio and blockage, which are more relevant to conical diffusers, are used in conventional design practice.
