7th Annual EuroFlam Seminar – Florence Italy 2000
Dates: Wednesday 21st and Thursday 22nd June 2000,
Location: Hotel Montebello Spendid, Florence - Italy.

Description:

The 7th Annual EuroFlam Seminar (Group FOTO) was attended by 11 Graduates/Visiting Investigators who presented their completed reports or progress reports. The meeting was also attended by the EuroFlam Management Committee augmented with a larger group of staff members from Cardiff.

The quality of presentations was generally of a high order and some interesting work was presented. The Academic and Industrial assessors, Prof. Hein and Dott. Ing Milani commented on the increasingly good quality. All of those who had completed their training/research period graduated and received their certificates of completion. The remaining speakers were assessed and will receive their certificates in due course.

This year the Best Presentation award (Certificate plus a cheque for €150), was given by the Italian Committee for Flame Research. Dr Giuliano Trebbi former Chairman of the Italian Committee attended the Thursday morning session and presented the award to Christian Skaug of Norway for his presentation “Large Eddy Simulation using G-Equations”. (Trebbi et al FOTO).

6th Annual EuroFlam Seminar – Cardiff University, UK 1999
Dates: Wednesday 23rd and Thursday 24th June 1999,
Location: Cardiff University.

Description

Visiting investigators from the three EuroFlam members, ENEL SPI, IFRF and Cardiff University, met together during the two days to present their reports on the projects that they had carried our during the previous year.

Seven European Countries were represented with ladies providing almost 40% of the participants.

The Programme

The research results presented covered a full range of subjects from basic research on coal combustion, analysis of liquid fuel sprays, excess enthalpy combustion through various mathematical modelling developments and applications to the development of innovative methods of 3D data presentation.

The presentations were assessed formally by the Industrial and Academic successors, respectively Professor Klaus Hein of TU Stuttgart, Germany and Dr Ambrogio Milani of CSM, Italy, and informally through active discussions following each presentation, extending through to the breaks. It was particularly noted that the quality of the presentations were higher than even, helped very much by the high standard of visual aids used.

The Air Products “Best Presentation” Award

In the past we have had the support of industry in terms participation of industrial IFRF Member Organisations at the seminars. This year for the first time we had support in terms of prize offered by British Flame Member Air Products. Roger Dudill, Air Products Main Contact Person in the UK, attended the technical sessions and based on the advice of the two assessors made the choice of the Best Presentation.

In his introduction, Roger confirmed the general difficulty in determining the best presentation due to the consistently high quality of the “top group”. But in the final analysis, the excellence of the presentation given by Elisabetta Carrea, the IFRF Graduate from the University of PISA, of on the subject “The role of char surface structure development in pulverised fuel combustion.” edged her in front of the of her colleagues.

Social Programme

The Conference dinner was held in the University on Wednesday evening. This meal was relatively informal. At the end of the evening, the Certificates of Completion were presented by Roger Dudill. But like all successful conferences, the real social programme extended well beyond the “organised” section!

Associated Management and Quality Control Meetings

The summer 1999 management meeting was held in parallel with the Visiting Investigator Round Table. Both contain a strong element of quality assurance. The round table meeting majors on this issue from the client point of view with a full report fed back to the Management Group.

The Conclusions

Dr Tony Griffiths Programme Manager at Cardiff, chaired the final session and took the opportunity to sum up the activities and achievement of the 1998/1999 EuroFlam year.

He briefly reviewed the breadth of scope embodied in the presentations, and congratulated the participants on their grasp of the complex issues under consideration. He went further to remind them of the tasks that lay ahead of them, particularly those that would remain working in fields relating to combustion.

He predicted that the Kyoto protocol and the need to provide innovative, cheap and effective heating processes technology for the control of carbon dioxide emissions would drive their work. In short Carbon Dioxide Control would form the basis of Combustion Engineering of the new millennium.

In any event the Staff at Cardiff must be congratulated for the fine organisation.
