Engineer Fluid dynamics Aeronautics Computing Education: Acharya Pathasala; University Visvesvaraya College of Engineering BEng (1953); Indian Institute of Science MEng (1955); California Institute of Technology PhD (1961) Career: California Institute of Technology; NASA Jet Propulsion Laboratory; Professor, Aeronautical Engineering department, Indian Institute of Science (1962-1999); Director, National Aerospace Laboratories (1984-1993); ISRO K. R. Ramanathan distinguished professor, Indian Institute of Science (1994-1999); Director, National Institute of Advanced Studies (1997-2004); Chairman of the Engineering Mechanics Unit, Jawaharlal Nehru Centre for Advanced Scientific Research, Bangalore (2000-2014); Pratt & Whitney Chair in Science and Engineering, University of Hyderabad Roddam Narasimha was a leader in fluid mechanical and aeronautical research in India. His ideas on the universal character of intermittency of turbulence and the evolution of turbulent spots led to improved understanding of the transition from the laminar to the turbulent state of fluid flow, and also of the reverse process of relaminarisation. Other research of lasting significance concerned fully turbulent wakes and boundary layers and the nature of bursts. In the field of rarefied gas dynamics, he made major contributions to constitutive relations for free molecule flow and shockwave structure, and put forward a novel theory for infinitely strong shocks. He also worked on practical aeronautics problems, and, for example, constructed a useful theory of performance variations in a system subject to repeated deterioration and maintenance. Professor Roddam Narasimha FRS died on 14 December 2020.
