Fundamental Concepts and Issues of Fluid Turbulence

A Thyagaraja
Visiting Professor, Chennai Mathematical Institute.


Fluid Turbulence, along with certain problems of solid mechanics, remains one of the last great unsolved problems of Classical Physics and Technology [not to mention Mathematics] despite intensive research from the time of Leonardo Da Vinci to the present day. In this Lecture, I shall outline the key concepts underlying the issues arising in its study which has ramifications ranging from the dynamics of the Universe to Earth's climate and weather and to a multitude of Engineering problems.

Extraordinary theoretical, computational and experimental advances made in the preceding three centuries have begun to lift the "fog" a little and have provided both qualitative and quantitative insights which are being used everyday in our lives. Although it is fair to say that Fluid Turbulence is not yet "fully understood" in the sense many classical [and quantum] areas of physics are, it may be hoped that mankind will grasp it sufficiently to deal with all practical problems in the not-too-distant future.
