Background

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 opening one in the Research Programme and is intended to set the scene for the subsequent work in the Programme. Leading industrial practitioners and leading specialists in turbulence will come together to outline the needs of industry for predictive methods for turbulence systems and to agree ways forward in addressing these needs.

Organisation

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:

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.

Copies of presented material 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.

For each technical area covered, the session will begin with presentations, identifying industrial problems and opportunities. This will be followed by a panel discussion to promote interaction between the industrial and academic participants in identifying turbulence modelling requirements and setting test problems. Finally, a rapporteur will sum up the main points from the session and will prepare a short written report which will serve as a general guideline and theme for the work of the Research Programme in this area.
