Help Desk Anonymous writes "Does anyone know the five best universities in CFD research named by NASA in 1980? I would appreciate your answer greatly.

I know one of them is ISU.

Thanks."

[Ed] I'm sure the top 5 has changed in 20 years. Any ideas about the best universities for CFD research today?

New Software: Open-source flow solver

Open Source Stephane Popinet writes "I am glad to announce the first "official" release of the Gerris Flow Solver (GFS 0.1.0). Gerris is an open-source, free-software library and code for the resolution of the three-dimensional partial differential equations describing incompressible fluid flow. Gerris can deal with arbitrarily complex solid boundaries in an automatic manner and uses dynamic adaptive mesh refinement to optimise the discretisation according to the flow solution.

The library can easily be extended through an object-oriented approach and is reasonably well documented.

Gerris is available free of charge under the terms of the Free Software Fundation General Public License (GPL).

Application: CFD Helps Increase Hot Oil Heater Output
Posted Mon June 17, 2002 @05:16PM
Print version Email story Tweet story
Application Computer simulation helped increase the output of a hot oil heater by 20%. The challenge was to increase the thermal output of the heater without causing the tubes that carry the oil to rise to such a high temperature that they or the oil would be damaged. Refinery engineers ran experiments that demonstrated that the existing burner layout in the heater would indeed overheat the tubes if run at the higher levels required to implement the desired production increase. Without simulation, the only viable option would have been to build and test a scale model of the heater, which would have been expensive and would not have provided much information as to what was happening inside. Instead, engineers used computational fluid dynamics (CFD) to analyze the flow within the heater, providing a clear understanding of the problem and making it relatively easy to find a solution. “CFD helped us zero in on the offending flow pattern which turned out to be an inversion of flue gas in the middle of the radiant chamber, pushing the flame towards the tubes.” said Jack Deng, Chief Technologist for Petro-Chem, New York, New York. “Once we understood the problem, we changed the burner configuration to break up the flue gas recirculation patterns, and straighten the flames.”

Petro-Chem is a privately held international organization providing design, engineering, development, fabrication and erection of direct fired heaters and heater accessories in the hydrocarbon processing, chemical processing and energy industries.

Post Processing MayaVi is a free, easy to use, scientific data visualizer. It is written in Python and uses the Visualization Toolkit (VTK) for the graphics. It provides a GUI written using Tkinter. MayaVi is free and distributed under a BSD license. It is also scriptable and cross platform and should run on any platform where both Python and VTK are available.

For more information, downloadable sources and binaries, screenshots, installation instructions, documentation etc. visit the MayaVi home page on SourceForge.

Also bundled with MayaVi is a VTK pipeline browser written in Python and a new utility module that makes using VTK easier from the interpreter.

Changes: A license change from GPL/LGPL to BSD, a new interactive data picker and light manipulation kit, a new CellData to PointData filter, Geomview OOGL export support, a few more commandline options, important bugfixes, PDF documentation, and new RPMs and debs.

New Software: Coolit V4.50

News Daat Research Corp. has added multiple processor capabilities to boost the calculating speed of its CFD thermal and flow analysis software, Coolit.

When installed into a multiple processor system, Coolit automatically recognizes the number of processors and parallelizes the computation accordingly. The result is a significant speed increase that ranges from a minimum of 1.5 times to almost double for dual processors. For more processors, speed gains are even greater.

This latest Coolit release, version 4.50, also incorporates numerous new features that aid the model building process and increase modeling accuracy. Most significant is the addition of new shapes to the component library. Tetrahedron, pyramid and spherical cap components join the previously released triangular prism components to make possible more complex shapes and more accurate geometries.

Other changes in the new release included greater editing flexibility, a wider range of component characteristics, and customizable projections in panel views. Coolit v.4.50 also implements a new advanced model for porous media. The new model is a significant improvement over the standard Brinkman model, which is used in most commercial CFD programs.

Coolit v.4.50 operates on all Windows-based platforms: Windows 95,98,2000,XP and NT. More information on Daat and Coolit can be found on the Daat web site.
