Whether in Industry or the Environment fluids are normally in turbulent motion. Engineers and physicists need to understand turbulent flows in order to develop means of predicting their behaviour and, thereby to account for their adverse effects or to exploit their potentially beneficial consequences.

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 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.

The Instructional Conference is an opportunity for young researchers to interact with the invited members of the INI Programme via a co-ordinated series of advanced lectures and informal discussions. The Instructional Conference will be held at the Isaac Newton Institute, 20 Clarkson Road, Cambridge CB3 0EH, UK (tel: 01223 335999, Fax: 01223 330508)

Theme of the meeting:

This meeting is suitable for post-doctoral and advanced pre-doctoral researchers working in the field of turbulence and transition modelling. The objective is to provide an integrated, state-of-the-art exposition of mathematical methods and techniques for characterizing the behaviour and consequences of turbulence as encountered in engineering and the environment.

Format: There will be typically five 1-hour lectures per day with ample time scheduled for more informal discussions. Participants are invited to contribute to poster sessions and/or open forum presentations on the theme of the conference. A book of the lecture material will be published.
