Application: CFD Modeling Advances Plant Safety Research

Application By Eckhard Krepper, Forschungszentrum Rossendorf, Germany

The Institute of Safety Research at the Forschungszentrum Rossendorf (FZR) focuses on safety assessments in nuclear plant and the chemical process industry. In this field, most of the passive safety components rely on natural convection to remove heat, and often involve large heat fluxes and boiling flows. We chose CFX-4 to help us in studying these flows because of its open interface that allows us easily to add our own models when required.

Before deciding on CFX-4, we undertook a number of validation projects. An example was the simulation of a scaled emergency condenser (NOKO) constructed in the laboratory of Forschungszentrum Jülich. We modelled the heat transfer from heated tubes in the primary circuit to the pool in the secondary circuit, accounting for the transient and laminar flow in the pool. CFX-4's calculation of the temperature stratification and the development of the plume were in good agreement with the experimental results.

Discretization maq writes "Finally I have finished my paper about three different methods for solution of incompressible NS equations:

Solution to two-dimensional Incompressible Navier-Stokes Equations with SIMPLE, SIMPLER and Vorticity-Stream Function Approaches. Driven-Lid Cavity Problem: Solution and Visualization. [compressed zip file]

I hope it will help somebody to understand SIMPLE, SIMPLER and Vorticity-Stream Function methods.

Please email me or reply there if you have any comments or suggestions. Anyway I am starting with developming software based on that method (user friendly, for windows, for educational purposes) so if you have any comments, suggestions - email me. "

News Companies are increasingly coming to depend on computer simulation ("virtual prototyping") to reduce development costs and get products to market faster. The role of NAFEMS in assisting these organisations to apply these techniques in an appropriate manner is expanding rapidly. In order to keep pace with this expansion, NAFEMS is pleased to announce the addition of Tim Morris in the role of Chief Operating Officer.

“Tim will play a leading role in driving the development of the organisation as it strives to reach its strategic objectives of greater internationalisation and wider technology support through revised products and membership opportunities” said Dr Paul Newton, Managing Director of NAFEMS.

Tim brings extensive experience of many different aspects of the implementation of engineering analysis techniques. Over the past fifteen years, he has been involved in a variety of roles involving sales and marketing, technical support, training, consulting work and general management.

AMD Opteron Ideal for Low-Cost CFD
Posted Thu May 01, 2003 @09:39AM
Print version Email story Tweet story
Hardware AMD's newly released Opteron CPU has a number of features which make it an ideal CPU for a low-cost multi-processor CFD compute server. Let's take a look at some of the features most useful for CFD computations.

Support for 32-bit and 64-bit operation

Many people are starting to bump against the memory address limitations of 32-bit computing when running large CFD calculations. Moving to 64-bit computing raises the memory address limit from 2^32 (4 gigabytes) to 2^64 (16 exabytes) although it should be noted that the Opteron uses 40-bit physical memory addressing putting the limit at 1 terabyte of physical memory. (An exabyte is 1,000 petabytes, a petabyte is 1,000 terabytes and a terabyte is 1,000 gigabytes.) Such a change will be essential for running next generation CFD problems utilizing millions of grid points.

But many CFD applications (grid generation, for instance) will be fine running in 32-bit address space for some time to come. This is where the Opteron shines because it can run both 32-bit and 64-bit applications natively, whereas the Intel 64-bit processor (the Itanium) uses an emulation layer to run 32-bit applications. The result is good CPU performance in both modes.
