News Pointwise recently added two new international distributorships to market and sell Gridgen, Pointwise’s computational fluid dynamics (CFD) meshing software. CODYSEC of Madrid, Spain and Anova of Istanbul, Turkey, will market, sell, and support Gridgen in their respective countries.

CODYSEC was founded in Madrid, Spain in 2002 to provide research, development, and innovative services to emerging technologies in Spain. They assist in developing products and processes through computer simulation. Additionally, they work to optimize industrial processes through the use of computer simulation. CODYSEC will distribute Gridgen in Spain and Portugal.

Anova is an independent company founded in 2003 providing fluid mechanics engineering software and services in Turkey. Their staff has an extensive technical background and has completed many fluid dynamics design and analysis projects. Their clients span the automotive, aerospace, marine, general industrial, and academic arenas, including such companies as Acerlik R&D, Mercedes-Benz Turkey, Ford Otosan, and Ataturk University. Anova is located in Istanbul.

Help Desk pgoyal10 writes "i am working on star-cd version 3.100B on windows 2000. i want to simulate melting in star-cd. since it is not possible to directly simulate melting in the star-cd, i am doing this by user subroutine specht.f. but when i give variable cp in the subroutine, the solution is erroneous. could you please suggest some remedy for it."

Application: Hatch uses CFX for Grinding Mill Analysis

Application by Ross Haywood,
Non-Ferrous Metals Technology,
Hatch Australia

Hatch, a leading global engineering organization, has a reputation for the successful scale-up of process technology and the implementation of innovative solutions to technical challenges. To fulfill this reputation, Hatch’s Non-Ferrous Metals Technology Group uses advanced analytical tools, in particular CFD, for design evaluation and optimization, scale-up analysis and problem solving, where heat transfer, fluid flow, combustion and mass transfer are critical issues.

Recently we confronted the problem of scale-up analysis of a multiphase grinding mill – essentially a multiphase turbomachine! The mill works by vigorously “stirring” the feed material (pulp) and a coarse solid grinding media using a series of concentric disks rotating at high speed. At the discharge, a stationary separator is used to allow the pulp to flow out of the mill while retaining the grinding media. The essential features of the problem, from a modeling perspective were: complex geometry; multiple frames of reference (rotating disks and a stationary outlet), and a multiphase flow. As an added complication, the flow is strongly swirling with tangential velocities nearly three orders of magnitude greater than the mean axial velocity through the mill; this seemed like a perfect fit (or worthy challenge) for the new capabilities of CFX-5.

CFD for Industrial Ventilation
Posted Fri February 20, 2004 @04:42PM
Print version Email story Tweet story
News The complexity of industrial ventilation design increases with the demands on the air quality in industrial premises. Also facility managers have to minimize the downtime of their plants due to modifications on installations etc. Nowadays, the methodology of virtual prototyping might be applied to industrial design tasks. It is a very helpful approach to achieve good ventilation solutions at low cost and minimized risk.

Air Flow Consulting published a paper at the Industrial Ventilation Conference 2003 (Winning the Award for Best Paper) on the subject of industrial ventilation titled "Virtual Prototyping and Virtual Reality in the Design Process of Industrial Ventilation". The paper [pdf] gives an introduction to virtual prototyping and the related topic of Virtual Reality. Finally, a case study shows how the virtual prototyping approach is used in the industrial ventilation design process. A mixing device in a chemical production plant was successfully retrofitted by local exhaust hoods. The aerodynamic concept was optimized using CFD.

CFD Provides More Answers on Shuttle Failure
Posted Fri February 20, 2004 @04:20PM

News CBS News is reporting that after months of testing and computer analyses, engineers believe they understand the phenomena that causes foam insulation to separate from the space shuttle's external fuel tank during launch. But preventing such foam shedding has turned out to be more difficult than originally thought, a top NASA manager said today, and tank modifications remain a major challenge.

Bill Readdy, NASA's associate administrator for spaceflight, said recertifying the external tank was at the root of a decision Thursday by senior managers to delay the first post-Columbia mission from September to March 2005.

"Return to flight has always been driven by fixing the tank because the tank was clearly the cause of the (Columbia) accident," Readdy told reporters. "An awful lot of what has been going on has been analysis of debris transport, how things that come off the tank (and are) transported from some area of the tank and then impinge on some other portion of the space shuttle stack.
