Research Programme on Turbulence
FUTURE STRATEGIES TOWARDS
Isaac Newton Institute for Mathematical Sciences, Cambridge, UK
June 29th-30th 1999
Turbulence is ubiquitous in industrial processes. Engineers need to understand turbulent flows in order to control them, design for their adverse effects or utilise them for best effect (as in mixing processes). In all cases, prediction is a necessary element in the engineering design calculations.
The development over the past 10-20 years of usable Computational Fluid Dynamics (CFD) codes has produced a sea change in the design and development approach, allowing products to be brought to the market much more rapidly and economically. However, CFD codes are necessarily based on turbulence models whose parameters have to be deduced from measurements. The generality of these parameters is questionable, and the mathematical aspects of the models have been inadequately explored.
The practical importance of turbulence has led The Royal Academy of Engineering to launch an Initiative on Turbulence, the most important outcome of which was the definition and agreement of a 6-month Isaac Newton Institute (INI) Research Programme to try to evaluate the fundamental issues and to develop a strategy to address these issues for the future. The Isaac Newton Institute is based in a purpose-built building which is designed to allow leading mathematical scientists to address together important issues in mathematical sciences.
This Symposium is the closing event of the Research Programme and is intended to define future strategies for ongoing work in the field. Presentations will be made relating to the various technical areas and to the respective application areas. Discussions will take place aimed at evaluating progress in the various technical areas and formulating future strategy.
The Symposium is being organised by the Industrial Working Party (representing The Royal Academy of Engineering) of the INI Research Programme on Turbulence, in collaboration with the Organisers of the Research Programme. The Industrial Working Party is as follows:
M.W. Reeks (Joint Research Centre, Ispra): Chairman
J. Coupland (Rolls Royce)R.P. Cleaver (BG Technology)
D.P. Hills (British Aerospace)
A.G. Hutton (DERA)
J.R. Noyce (BNFL/Magnox Electric)
M.J. Rabbitt (British Energy)
D.J. Thomson (Met. Office)
The Organisers of the INI Research Programme are as follows:
J.C. Vassilicos (DAMTP, Cambridge)
G.F. Hewitt (Imperial College, London)
P.A. Monkewitz (EPF, Lausanne, Switzerland)
N.D. Sandham (Queen Mary & Westfield College, London)
The Symposium will be held at the Isaac Newton Institute, 20 Clarkson
Road, Cambridge, CB3 0EH, UK
(Tel: 01223 335999, Fax: 01223 330508)
A book containing the presentations will be issued to all delegates and lunches on the two days, a dinner on the first day, accommodation for one night and coffee will also be provided. To cover the costs of these items, a fee of £150 will be charged to registrants. Support towards this fee may be feasible for UK Academics who should apply to INI for details.
The Symposium is open to all those who are interested in the field, but participation from those involved in predicting industrial turbulent flows will be particularly welcomed.
The Symposium will begin with a presentation of the state-of-the-art in each of the major technical areas. This will be followed by presentations from industrial participants surveying what has been achieved in the Research Programme and what the priorities should be to advance prediction methods.
