Turbulence in fluid flow has remained one of the challenging problems of science and engineering today. Although important advances have been made in our knowledge of the process of turbulence since the time of Obsorne Reynolds more than one hundred years ago, our current ability to accurately predict turbulent events and their properties is still very limited in all but simple flows. The mathematical complexity of the Navier-Stokes equations has so far prevented the development of a comprehensive theory of turbulence that will facilitate their solution. Increasingly, turbulence researchers have turned to numerical tools in their search for solutions to problems of practical concern. Indeed, interest in turbulence is not all about idle curiosity. Most flows of technological significance are turbulent. Turbulence promotes air-fuel mixing that is crucial for efficient combustion in engines, but is also responsible for energy-losses in flow-related transport systems. Turbulence is a source of noise and its presence in the atmosphere poses hazards for air travellers. A greater understanding of turbulence and an improved ability to predict its characteristics are essential for mastering control of turbulent flow and managing turbulence-related energy losses. Turbulence research has continued to attract and engage the keen interest and effort of engineers, physical scientists and mathematicians because of its practical relevance and intellectual challenge.

The turbulence program will comprise a series of seminars, tutorials and workshops extending over the period from July to December 2004 at the Institute for Mathematical Sciences of the National University Singapore. The program will focus on the following themes:

• Theoretical Developments in Navier-Stokes Equations & Turbulence Research
• Computation of Turbulence
• Turbulence at a Free Surface
• Transition & Turbulence Control

There will be selective bias towards turbulence at surfaces, since this is most commonly encountered in applications.

The activities of the program include:

1. Workshops
