Professor Roddam Narasimha’s major interests have been in fluid dynamical problems associated with
aerospace technology and atmospheric sciences. A connecting link between the two is that turbulent fluid
flow plays an important role in both fields.

In aerospace problems, fully turbulent flow and the transition to and from that state are at one and the same
time of both practical and fundamental scientific interest. Turbulence has remained ‘the chief outstanding
difficulty of the subject’ for about a hundred years. Transition from laminar to turbulent flow, as well as
the less widely studied reverse transition from turbulent to laminar, have been a major area of Narasimha’s
research. In the atmosphere turbulent flow in the tropics has a strongly convective character, and the laws
governing it at low winds are of great interest in monsoon predictions. There is the intriguing question of the
possible connections between monsoon rainfall and solar processes. There is also the basic question of the
mix of order and disorder in turbulent flow - in technology as in nature, and of the possibility of teasing out
the order from chaos using wavelet techniques. Fluid flows remain fascinating because of their diversity, and
of their fundamental scientific interest as well as their technological applications.

Professor Roddam Narasimha, FRS, Chairman of the Engineering Mechanics Unit, JNCASR and Director,
National Institute of Advanced Studies, Bangalore is one of India’s most eminent scientists. His work on
atmospheric sciences and aerospace technology is known the world over. This is evidenced by his many
publications and the many national and international awards he has obtained.

This yearly oration is given by a distinguished Indian public figure to enhance and promote understanding
and friendship between Australia and India under the active patronage of India's President.
