Help with Rod Bundle Array Flow
Posted Thu May 12, 2005 @04:53PM
Print version Email story Tweet story
Help Desk Arnie writes "hi

I have this problem in which I have an array of rod bundles. All of them heated. Cooling water is flowing axially through the array. Some of the rod bundles are not heated but have perforations on their periphery through which more cooling water flows in a direction normal to the main axial flow. I want to know regarding analysis of this problem i.e., how do I proceed towards getting an analytical solution to the problem.

If you have any idea about the influencing parameters, please let me know.

Thanks in advance....
waiting for your response...

Events: Visit CD-adapco at the 46th International Paris Air Show

News CD-adapco, the leading provider of CAD-embedded flow simulation solutions today announced their participation at the 2005 Paris Air Show, the leading international event for the aviation, aeronautics and space industries, taking place at Le Bourget Airport, France, from June 13 - 19, 2005.

The use of CFD in the aerospace community has evolved. No longer viewed as a replacement for wind tunnel experiment, CFD has gained a reputation as a powerful tool for creative design. However, CFD is increasingly required to earn the title of a responsive mainstream tool, providing information within the restrictive timescales of the design process. Previously CFD engineers were able spend months constructing a mesh for a complete aircraft simulation, however competitive pressure means that now the entire aircraft polar needs to be simulated in just a few days. In order to meet this challenge, aerospace companies are increasingly turning to commercial CFD solutions. One such solution is CD-adapco's newly released flagship code: STAR-CCM+.

News Racing Fan Magazine has posted a story on the use of CFD in the design of a new Dodge car to compete for the NASCAR Winston Cup.
CFD has accelerated the whole design process. According to Jean-Michel Esclafer de La Rode, Dodge's chief CFD manager, "Drafting studies [that once] took a couple of weeks to simulate, we can do in a few days today."

Application CAD Server has posted an article on the design of a new low-cost Unmanned Aerial Vehicle. The article mentions that the craft was designed extensively using CFD.
In the words of Daniele Camatti, CEO of ProS3 and designer of the Pro Observer: "CFD analyses performed with STAR-CCM+ were critical in determining if the initial airframe designs were good enough to ensure the required flight performance. With STAR-CCM+ we were able to estimate with great precision the position of the aircraft's aerodynamic center, to such an extent that, from the first test flight onwards, we have completely avoided crashes."

Upfront CFD: How to Grow Its Adoption
Posted Mon May 09, 2005 @09:39PM
Print version Email story Tweet story
News Desktop Engineering is running an article where they asked several cfd vendors how to increase adoption of "upfront" CFD, that is, use of CFD during the design phase of product development.
Overall, the participants agreed that greater awareness of the potential benefits and the tools available would be important to the next growth spurt. They also agreed that more intelligence built into the software would help drive this market—and that the availability of faster low-cost computer platforms and inexpensive memory were already helping to grow the market.

One vendor was quoted as saying “The upfront tool is meant for initial analyses, using the native CAD model. It does automatic meshing, and this avoids the biggest area of possible error”.
