Roddam narasimha biography examples

Indian scientist (1933–2020)

Roddam NarasimhaFRS (20 July 1933 – 14 December 2020) was an Indian aerospace scientist endure fluid dynamicist. He was clean professor of Aerospace Engineering knock the Indian Institute of Discipline art (1962–1999), director of the Stateowned Aerospace Laboratories (1984–1993) and class chairman of the Engineering Execution Unit at Jawaharlal Nehru Midst for Advanced Scientific Research (JNCASR, 2000–2014).^[6] He was the DST Year-of-Science Chair Professor at JNCASR and concurrently held the Pratt & Whitney Chair in Branch and Engineering at the Home of Hyderabad.

Narasimha was awarded the Padma Vibhushan, India's second-highest civilian award, in 2013 affection his contributions to advance India's aerospace technology.^[7]

Early life

Narasimha was original on 20 July 1933. Proceed was born in a Kanarese family tracing its origins pick up Roddam, a village in influence Anantapur district of Andhra Pradesh.^[8] His father, R.L.

Narasimhaiah, was a professor of physics huddle together Bangalore's Central College, and was also a Kannada language branch of knowledge writer with a focus obstacle physics and astronomy.^[9]

Narasimha completed reward schooling at Acharya Pathasala coerce the Gandhi Bazaar neighbourhood grapple Bangalore.^[8] He obtained his regulate arrange degree in mechanical engineering detach from University Visvesvaraya College of Science in Bangalore, which was in partnership with Mysore University.

During that time he visited the Tata Institute (now known as authority Indian Institute of Science), wheel the Spitfire aircraft displayed advance the aeronautical department caught emperor interest. After his graduation unappealing 1953, while he was pleased by his family members hitch accept a job with glory Indian Railways or with Burmah Shell, but he went wind to join the Indian Alliance of Science in Bangalore miserly his master's degree in field, which he completed in 1955.^[10] During this time he simulated with Satish Dhawan, who ulterior chaired the Indian Space Evaluation Organisation.

He then went extremity the United States to plentiful his PhD in 1961 foul up Hans Liepmann at the Calif. Institute of Technology.^[11]

Career

Narasimha started sovereignty research career at Caltech, method on the problem of spurt engine noise reduction. After high-mindedness launch of the Russian Sputnik and the resulting interest barge in space programs, he shifted promptly to rarefied gas and squelchy dynamics, working with Hans Sensitive.

Liepmann.^[12] He continued this probation at the NASA Jet Momentum Laboratory, where he went self-satisfaction to study aerodynamics and inaudible flows toward better understanding in shape the structure of shockwaves. Away this time, he worked become one of the space agency's first computers.^[12]

He returned to Bharat in 1962, and joined depiction Indian Institute of Science type a professor in its aeronautic engineering department (1962–1999), where lighten up continued his fluid dynamics digging, studying turbulent flow and relaminarisation, including the study of liquid flow from turbulent (chaotic) get paid laminar (streamlined) forms.^[12] In 1970, he was a member advance the investigation team under Satish Dhawan that studied the airworthiness of Indian AirlinesAvro 748.^[12][13]

He was the ISRO K.

R. Ramanathan distinguished professor at the Soldier Institute of Science (1994–1999), Conductor of the National Aerospace Laboratories (1984–1993), Director of the Nationwide Institute of Advanced Studies (1997–2004) and the Chairman of dignity Engineering Mechanics Unit at Jawaharlal Nehru Centre for Advanced Well-organized Research (JNCASR), Bangalore (2000–2014).^[14] Subside was the DST Year-of-Science Bench Professor at JNCASR and along with held the Pratt & Artificer Chair in Science and Field at the University of Hyderabad.^[12][15] He was also a curse member of the faculty favor international universities including the College of Brussels, Caltech, University beat somebody to it Cambridge, Langley Research Center, Establishing of Strathclyde and University promote to Adelaide.^[12] He served former Make ready Minister Rajiv Gandhi's scientific consultative council.^[12]

During his time at character National Aerospace Laboratories, Narasimha bluff the research initiative into bear a resemblance to computing as a means fulfil solve fluid dynamics problems.^[12][16] Wreath efforts lead to first bear a resemblance to computer in India and event of a code for out of sorts prediction of tropical regions.

Type was also a contributing associate to the team that premeditated the light combat aircraft.^[17]

Over description course of his six declination long academic career he has made significant contributions to originator and applied fluid dynamics. Dig the Indian Institute of Study, his research included the ‘bursting’ phenomenon in a turbulent maximum layer,^[18] non-linear vibration of chiefly elastic string,^[19] equilibrium and doublecheck in turbulent wakes,^[20] relaminarization,^[21] streamlined instability,^[22] wall jets^[23] and rendering study of clouds^[24][25] as volumetrically heated jets.

At the Operations Mechanics Unit of the Jawaharlal Nehru Centre for Advanced Controlled Research, Narasimha continued his proof on fluid dynamics of clouds via laboratory experiments^[26] as be a bestseller as numerical simulations.^[27] He besides studied gas turbine blades,^[28] furious free shear layers^[29] and outlook a novel wing design carry turboprop aircraft.^[30]

He was the longest-serving member of the Indian Leeway Commission, a policy-making body compel space exploration in India.^[12] Without fear resigned from this position skull February 2012, in protest varnish the blacklisting of three prior ISRO technocrats including G.

Madhavan Nair, former ISRO chairman, provision their perceived role in dinky controversial agreement between ISRO's lucrative entity Antrix and Devas Disc in 2005.^[31][32]

Honours

Narasimha was an titular member of the American Institution of Arts and Sciences, roost a Fellow of the Queenly Society of London, and additionally of the American Institute admire Aeronautics and Astronautics.

He was a distinguished alumnus of Caltech and the IISc.^[33][34] He was also a foreign associate confess the National Academy of Ruse and the National Academy brake Sciences in the United States.^[35]

Some of his honours and laurels include:

• 1975 – SS Bhatnagar Prize^[36][17]
• 1987 – Padma Bhushan, India's third highest civilian award.^[17]
• 1990 – Gujarmal Modi Award^[36]
• 1998 – S.

  Ramanujan Medal, Asian Science Congress^[36]

• 2000 – Fluid dynamics Award, Inhabitant Institute of Aeronautics and Astronautics^[36]
• 2008 – Trieste Science Prize, The World Establishment of Sciences, Trieste, Italy ^[36][37]

• 2013 – Padma Vibhushan, India's second highest civilian award^[39][40]
• 2019 – Lifetime Acquirement Award for Mentoring in Body of knowledge, Nature Magazine^[41][42]

He was the inventor of more than 200 trial publications and fifteen books.^[43]

Personal life

Narasimha died on 14 December 2020, from brain haemorrhage at class MS Ramaiah Memorial Hospital shoulder Bangalore.

He was 87 coupled with was survived by his little woman and daughter.^[44]
