The QNET-CFD Thematic Network aims to improve the quality of industrial CFD calculations, and to increase the level of trust in the results obtained by CFD. The principle objective is to collate and structure existing knowledge on industrial CFD simulations in the form of a Knowledge Base, and to facilitate the exchange of experience and know-how for this generic technology across different industrial sectors.
The QNET-CFD Thematic Network has 44 partners from 8 EU member states, 1 EFTA member state, and 2 pre-accession states. The QNET-CFD Network is managed by the University of Brussels, with WS Atkins in the UK as assistant co-ordinator. The network is organised around 6 industrial sectors:
· Thematic Area 1: External Aerodynamics
· Thematic Area 2: Combustion and Heat Transfer
· Thematic Area 3: Chemical and Process, Thermal Hydraulics and Nuclear Safety
· Thematic Area 4: Civil Construction and HVAC
· Thematic Area 5: Environment
· Thematic Area 6: Turbo machinery Internal Flows
Sulzer Innotec is thematic area co-ordinator responsible for the Thematic Area 1. In the first half year of the project, each member of QNET-CFD had to define at least one Industrial Application Challenge for further analysis during the project. An application challenge is defined as an industrial CFD problem which is of key importance to the industrial sector, and where CFD and experimental data are available. Sulzer Innotec proposed a test case based on experimental work on a planar diffuser rig in EPFL Lausanne. In the second half year of the project, each partner had to improve the documentation for the Application Challenge using the Guidelines provided by the QNET Quality and Scientific Co-ordinators. In addition, each QNET-CFD partner had to review at least one Application Challenge proposed by another member of his Thematic Area. Sulzer Innotec reviewed the Application Challenge submitted by AEA Technology (Hydro Vevey Pump Turbine). Work also began on the preparation of the annual state of the art review of CFD for Thematic Area 6 and preparation of a presentation for the first Workshop in Athens on 10 and 11 May, 2001.
As Coordinator for the Thematic Area 6, Sulzer Innotec contributed to the QNET-CFD Bulletin, which was published in February 2001, and took active part in two QNET-CFD meetings which were organised in 2000, the Kick-Off meeting in Brussels in May, and the first Progress meeting at DERA in the UK in November. In addition, together with the quality co-ordinator of the QNET-CFD network, Sulzer Innotec published two technical papers on the subject of quality and trust in industrial CFD, one presented by Dr Hutton of DERA at the AIAA conference in Reno (January 2001) and the other presented by Dr. M Casey at a VDI workshop in Germany (February 2001), see references below. Contacts were also started with the ERCOFTAC special interest group on turbomachinery with regard to the organisation of a joint workshop early in 2001.
