The 4th International ASME/JSME/KSME Symposium on
COMPUTATIONAL TECHNOLOGY (CFD) FOR FLUID/THERMAL/CHEMICAL/STRESS SYSTEMS WITH INDUSTRIAL APPLICATIONS
ASME PVP Division Conference is scheduled for August 4-8, 2002
at the Hyatt Regency, VANCOUVER, CANADA
The Symposium will be an exciting opportunity for CFD researchers to share
ideas and to explore new concepts and innovations.
Based on abstracts already submitted (> 60), we are delighted to report
that there will be a good mix of top quality papers from industry,
government labs and academe with very strong representation from Europe,
Pacific Rim, Asia.
Symposium is conducted on bi-annual schedule (next is scheduled to 2004)
and this time it is organized by the ASME jointly with Japaneese Society of
Mechanical Engineers (JSME)and Korean Society of Mechanical Engineers
KSME).
We expect to have 60-80 papers presented at the Symposium
and another 100+ papers presented on fluid, thermal and stress related
symposiums. Best papers will be recommended for the journal publications.
Due to the many requests for extensions, deadline (for Americas only) for receipt of abstracts WAS MOVED to January 25, 2002. Corresponding
deadline for the reception of draft papers is moved to Feb 28th.

By adding computational fluid dynamics (CFD) analysis to its product development process, Blender Products was able to design a new HVAC air mixer in four weeks, down from the one year required for its previous mixer. Designing that product had required many rounds of prototype testing, each taking several months, to determine how efficiently the device mixed two streams of air. For the new mixer, the company ran multiple CFD analyses to evaluate different design iterations in software. Each iteration took less than a week. The results guided designers as to what elements could be removed to reduce manufacturing costs while maintaining mixing efficiency. Nearly all prototype testing was eliminated, allowing Blender Products to quickly capitalize on a new market opportunity. The company also uses CFD analysis to evaluate how its mixers will work when added to existing installations. This formerly required testing of a scale model, a process that took two to three months. The company now accomplishes the evaluation without a scale model and is done in one week.

Philadelphia Mixers used MixSim, a dedicated mixing analysis software package, to solve a problem with a pH adjustment system in a baffled mixing tank. The complete analysis, which required several simulations, took only one day, considerably less than the week or more that would have been required if general-purpose computational fluid dynamics (CFD) software and grid generation tools had been used. Most of this time would have been required to build the model because of the complex geometry of the system and the fact that it contained both stationary and moving parts. The mixing-specific software used set up the model automatically in response to parameters entered by the user. "After I entered a few specifications, the software created the geometry and the analysis mesh in less than 5 minutes," says Wojciech Wyczalkowski, director of technology at Philadelphia Mixers. After the first analysis showed the reason for the fluctuating pH, Wyczalkowski ran seven more analyses to improve the design. By the end of one day, he had an optimized solution that the customer has since implemented successfully.

This week's CFD haiku comes from Russia:
Adaptive grid, unknown solution
Watching residuals... A question in mind:
What I am doing here?
Send in your CFD haiku for publication here each week. There is no reward other than perhaps personal enlightenment. So, silence the mind, yield to spontaneity and send in your CFD haiku today.
