The QNET-CFD Network

The EU Network on Quality and Trust in the Industrial Application of Computational Fluid Dynamics was a four-year project which brought together the expertise of 43 participating organisations across Europe. The main objective of the Network was to improve the level of trust that can be placed in industrial CFD calculations by assembling, structuring and collating existing knowledge encapsulating the performance of models underlying the current generation of CFD codes.

The membership was principally built from industry, although there was a strong representation from universities and national research organisations and from the major European CFD code vendors. The network was co-ordinated by the University of Brussels (VUB), with WS Atkins plc acting as assistant co-ordinators. The Network was organised around six Application Areas; between 2000 and 2004 it created a Knowledge Base containing 43 Application Challenges and 43 Underlying Flow Regimes.

Following the end of the EU Network in July 2004, the Knowledge Base passed to the control of a committee of ERCOFTAC, the European Reserach Community of Flow, Turbulence and Combustion, with the remit of enhancing and expanding the Knowledge Base and bringing it online for the benefit of applied Fluid Dynamicists and CFD users worldwide. The Knowledge Base continues to welcome new Application Challenges, Underlying Flow Regimes and entire Application Areas as part of a continuous process of updating with enhancement of its quality, depth and scope.

The QNET-CFD Knowledge Base

This Knowledge Base is a shared database of computational and experimental results to support industrial CFD applications. The QNET-CFD Knowledge Base comprises:

  • A library of the industry-specific Application Challenges, documented by QNET-CFD contributors.
  • Information on a series of well-documented Underlying Flow Regimes: generic flow regimes which form the building blocks of the full industrial applications.
  • Best Practice Advice that distils the experience of the European community of specialists into guidelines for assessing and enhancing the quality of CFD simulations.
  • State-of-Art Reviews on the application of CFD for each industry sector.

All entries into the knowledge base have to undergo rigorous quality checks against standards that have been developed and refined during the course of the project by the Quality and Scientific Coordinators Prof. T. Hutton and Prof. W. Rodi.
