Elected Academician of the International Eurasian Academy of Sciences on 7 May 2015, the late Professor Tov Elperin (1949–2018) was a distinguished Israeli physicist and mechanical engineer whose work made fundamental contributions to the understanding of turbulence, multiphase flows, and the transport of particles and scalars in geophysical and engineering systems. Born in Minsk, then in the Soviet Union (now Belarus), he studied physics at Minsk University before receiving his Ph.D. from Ben-Gurion University of the Negev in 1984. Early in his research career, he worked at Cornell University under Professor S. B. Pope, one of the leading figures in modern turbulence research, before joining the faculty of Ben-Gurion University that same year. He remained there throughout his academic career, founding and directing the Laboratory of Turbulent Multiscale Flows in the Department of Mechanical Engineering and establishing it as an internationally recognised centre for experimental and theoretical turbulence research. He also played a key role in developing interdisciplinary undergraduate and master’s programmes integrating engineering and physics. His long-standing collaboration with Professors Nathan Kleeorin and Igor Rogachevskii led to influential advances in turbulence physics, including the prediction and experimental verification of turbulent thermal diffusion, the elucidation of small-scale particle clustering in stratified and non-stratified turbulence, and the demonstration that chemical reactions can substantially modify the turbulent transport of aerosols and gases.
