Description |
Fluid turbulence, and the transition from a laminar to a turbulent flow, is probably the most important unsolved problems in physics, more than a century after it was first discovered. The distinction between laminar and turbulent flows, and the characteristics of turbulent flows, will first be reviewed. This will be followed by a discussion about why fluid turbulence is difficult to understand, but also essential for life as we know it. The transition to turbulence due to hydrodynamic instabilities is well understood in some flows, such as rotating flow and fluids heated from below, and the routes to turbulence in these kinds of flows will be discussed. The transition is poorly understood in simple flows such as pipe flows; the reasons for these will be highlighted. Some of our work in understanding turbulence at small scales will be discussed. The talk will be at a basic level accessible to all. About Prof. V.Kumaran: Prof. V.Kumaran did his B.Tech. from IIT Madras (1987) and Ph.D. from Cornell University (1991) both in Chemical Engineering. Among the awards and honours he won are JC Bose National Fellowship (2007), Swarnajayanti Fellowship (2002), Bhatnagar Award (2000), Amar Dye-Chem Award (1999), Indian National Academy of Engineering Young Engineer Award (1997) and Indian National Science Academy Young Scientist Medal (1996). He is a fellow of Indian National Academy of Engineering (2006), Indian National Science Academy (2001) and Indian Academy of Sciences (1998). Prof. Kumaran serves on the editorial boards of Soft Materials, Sadhana and Indian Journal of Chemical Technology as well as on the advisory Board of Acta Mechanica journals. |
