Robert Anthony Antonia FAA (born 2 July 1943) is an Australian engineer and academic who is Emeritus Professor of Mechanical Engineering at the University of Newcastle.[3] He is known for his experimental and theoretical research in turbulent flows, including work on surface roughness effects, turbulent boundary layers, scalar transport and small-scale turbulence.[1] In 2004, he was elected a Fellow of the Australian Academy of Science.[1] In 1977, he received the Edgeworth David Medal of the Royal Society of New South Wales for contributions to fluid mechanics.[2]
Early life
Antonia was born in Egypt in 1943. During the 1956 Suez Crisis, his family relocated to Bayonne, France, where he undertook part of his secondary education. In 1958, the family migrated to Australia, and he completed his secondary schooling at De La Salle College, Ashfield, Sydney, where he was dux of the college in 1959.[3][not in citation given]
Education
Antonia studied at the University of Sydney, where he earned a Bachelor of Engineering (Honours) in 1964, a Master of Engineering Science in 1965, and a PhD in 1970.[3] His doctoral research, supervised by R. E. Luxton, examined the response of turbulent boundary layers to changes in surface roughness.[citation needed]
Career
After completing his PhD, Antonia undertook postdoctoral research in the Department of Aeronautics at Imperial College London under Peter Bradshaw.[3] He later returned to the University of Sydney as a lecturer and senior lecturer before joining the University of Newcastle in 1976 as Professor of Mechanical Engineering.[3] From 2001 to 2005, he held an Australian Research Council Professorial Research Fellowship, and in 2006 he was appointed Emeritus Professor at the University of Newcastle.[3][not in citation given]
He participated in turbulence research collaborations with institutions including Imperial College London, NASA Ames Research Center, the University of California San Diego, the Norwegian Institute of Technology, Sapienza University of Rome, the Japan Aerospace Exploration Agency, and research institutes in France, Canada and China.[3][not in citation given]
Research
Antonia's research has focused on experimental and theoretical aspects of turbulent flows, including turbulent boundary layers, surface roughness effects, scalar transport and small-scale turbulence.[1] His work examined the response of turbulent boundary layers to sudden changes in surface conditions such as roughness, heat flux and suction. He also contributed to the identification of organised motions in turbulent shear flows using conditional sampling techniques and temperature as a tracer.[1]
A significant aspect of his work involved the development of analytical frameworks for comparing velocity and passive scalar fluctuations in turbulent flows. His research also utilised direct numerical simulation datasets to improve the measurement and interpretation of spatial velocity and temperature derivatives in turbulence.[1]
Later work by Antonia and collaborators investigated finite Reynolds number effects in turbulence and their relationship to the similarity hypotheses proposed by Andrey Kolmogorov in 1941 and 1962.[4][5] These studies, based on scale-by-scale energy and scalar variance budget equations, interpreted experimental and numerical results as broadly consistent with Kolmogorov's 1941 theory while questioning aspects of the 1962 refinement at finite Reynolds numbers.[6]
