NPC3

This is a report from the third annual meeting of the Nordic PC, which was held in Majvik, Finland August 26-28, 1998.

First of all I would like to thank all of the participants for a successful meeting. It was very good to get an insight into what is going on in the area of industrial computational fluid mechanics in the Nordic countries. For those who were not there a list of participants and a copy of the program is included at the end of this file.

In addition to the research seminars, information about ERCOFTAC activities during the past year was given as well as discussion of the future activities of the Nordic PC. A short summary is given below.

1) The Nordic Pilot Center was reviewed by the ERCOFTAC organization during the past year. It received a good review and is one of the more active ones in the organization. There will be a report about the Nordic PC in the December issue of the ERCOFTAC Bulletin, to which all members are welcome to contribute.

2) ERCOFTAC is publishing its own scientific journal called "Flow, Turbulence and Combustion". It is published by Kluwer and replace "Applied Scientific Research". The first issue will appear during fall of 1998.

3) Rolf Karlsson described the Industrial Action Committee (IAC) initiative on Quality and Trust in CFD. Many industries in Europe are participating and Rolf encouraged increased participation from Nordic industries.

4) The Second Summer school on Turbulence and Transition Modelling took place at KTH June 10-16, 1998. The invited speakers were Danial Arnal, ONERA, Uwe Dallmann, DLR, Rainer Friedrich,TU Munich, Sanjiva Lele, Stanford, Olivier Matais, Grenoble, Jim Riley,Univ Washington. See the full announcement/report at the Nordic PC homepage.

5) A revived SIG 2 on Turbulent Boundary Layerswere described by Arne Johansson. Arne together with Bertrand Aupoix at ONERA are heading that activity, which has received a lot of interest.

6) The new special interest group called "Laminar-Turbulent Transition Mechanisms, Prediction and Control", organized by Germany North PC and the Nordic PC, will have a meeting in Gottingen Sept. 14-17, 1998. See the full announcement at the Nordic PC homepage.

7) A workshop on CFD for flows in water turbines will take place at Porjus, Sweden, June 20-23, 1999. See the full announcement at the Nordic PC homepage.

8) The next annual meeting will be in Trondheim, Norway. Preliminary dates are August 26-27, 1999.

Thanks again for a good meeting,

Dan Henningson, Coordinator
