A scientific seminar dedicated to the 125th anniversary of Lev Loitsyansky was held in the first academic building of Peter the Great St. Petersburg Polytechnic University.
Lev Gerasimovich Loitsyansky (December 13 (26), 1900 – November 3, 1991), professor, Honored Scientist and Engineer of the Russian Federation, a leading expert in boundary layer and turbulence theory, and the author of fundamental monographs and textbooks on fluid dynamics and theoretical mechanics, is among the most outstanding Russian mechanical scientists of the 20th century. A key milestone in L. G. Loitsyansky's biography was the establishment, on his initiative in 1935, of the Department of Hydroaerodynamics at the Leningrad Polytechnic Institute, which he headed for nearly four decades.
Lev Loitsyansky published over 120 original scientific papers in a wide variety of areas of fluid and gas mechanics: the theory of laminar and turbulent boundary layers, the statistical theory of turbulence, the semi-empirical theory of turbulence, the theory of viscous fluid jets, the theory of gas lubrication, etc. Many of these became fundamental in the development of entire areas of fluid dynamics.
The textbook "Mechanics of Liquids and Gases" prepared by L. G. Loitsyansky for universities has gained widespread recognition. The first of its many editions dates back to 1950, and the last, seventh, to 2003. In our country, this book remains one of the main textbooks and a recognized scientific guide in this field for students, graduate students, and engineers.
More than 100 people took part in the scientific seminar organized by the Institute of Physics and Mechanics (PhysMech) of SPbPU: students of Lev Gerasimovich, teachers and staff of PhysMech, primarily the Higher School of Applied Mathematics and Computational Physics (HSAMCP), other divisions of the university, scientific and educational organizations of St. Petersburg (SPbSU, Voenmech, St. Petersburg State Marine Technical University, St. Petersburg State University of Civil Aviation, Krylov State Research Center, VNIIG named after B.E. Vedeneyev and others) and Moscow (TsAGI), graduates of the Department of Hydroaerodynamics, postgraduate students and students of HSAMCPCP.
The event's goal is not simply to pay tribute to this outstanding scientist and educator, but also to analyze how his fundamental ideas influenced the development of modern science and technology.
Vladimir Glukhov, an advisor to the rector's office and a 1970 graduate of the Physics and Mechanics Faculty (Department of Mechanics and Control Processes), addressed the seminar participants with a welcoming speech. He noted Lev Gerasimovich's caliber as a scientist and his importance to the university. According to Vladimir Viktorovich, Loitsyansky was a brilliant teacher and always treated students warmly, even if they studied in other departments.
The seminar program included thematic presentations by SPbPU professors, invited representatives of scientific organizations, and high-tech industry organizations—graduates of the Department of Hydroaerodynamics.
