THE

S. S. KUTATELADZE)CCASION OF HIS SIXTY-FIFTH

ON 18 July 1979 was the sixty-fifth anniversary of thefull Member of the U.S.S.R. Academy of Sciences
Professor Samson Semenovich Kutateladze.
His first
monograph“Fundamentalsof Heat Transfer Theory
During a Change of Aggregation
States” was published 40 years ago, and this work of a young author
immediately attracted the attention of scientists by its
originality, its audacious approach to the solution ofcomplicatedproblems and by the depth of physicalintuition.
Since then, the works of S. S. Kutateladze
havegained much world recognition.
In 1969, for his
eminent contributions
to the science and art of heattransfer,
he was presented
with the Max Jakob
Memorial Award by the American Society of Mechanical Engineers and the American Institute of Chemical Engineers.

ANN1:RSARY

S. S. Kutateladze
is one of the organizers and amember of the Assembly of International
Conferenceson Heat Transfer, also a member of the Honorary
Editorial Advisory Board of the International
Journalof Heat and Mass Transfer. He is the author of 14books, some of them being translated and published in
the United States, Great Britain and Czechoslovakia.
One of the most important contributionsof S. S.
Kutateladze is the discovery of similarity conditions inthermohydrodynamic
processes during a change ofaggregation
states and the developmentof the hydrodynamic
theory of heat transfer crises in boilingliquids. Later on, the principle of flow analysis in termsof the hydrodynamic
stability was used to define theconditions for various gas-liquidflow regimes. S. S.
Kutateladze
actively participatedin the studies todevelop Soviet atomic energetics. Under his leader-

ship, a series of theoretical and experimental studies onheat transfer in liquid metals were performed.
Starting in the fifties, S. S. Kutateladze has given
much attention in his studies to the hydrodynamics of
single-phase liquids, primarily to the theory of wall
turbulent flows. In 1959, he discovered the existence ofthe finite value of relative friction factor with infinitely
increasing Reynolds number. In cooperation with A. I.
Leontiev, he developed the theory of a turbulent wallboundary layer with vanishing viscosity. In particular,
in terms of this theory several fairly simple calculation
formulae were obtained taking into account the influence of pressure gradient, diffusion, non-isothermality and compressibility of flow on the friction andheat transfer.
Institute of Thermophysics
Academy of Sciences of theU.S.S.R.-Siberian Branch,
Nooosibirsk

S. S. Kutateladze has always combined his scientificactivity with teaching. He heads the Department ofThermophysics at the Novosibirsk University. Morethan 80 of his pupils have been awarded doctors’ andcandidates’ degrees.
S. S. Kutateladze has celebrated his sixty-fifth
anniversary in the prime of his creative power. At
present, he is the Director of the Institute of Thermophysics (Siberian Branch of the U.S.S.R. Academy ofSciences, Novosibirsk). His keen sense of the new andthe rejection of traditional ways to solve problems
create an atmosphere of continuous scientific search inthe Institute which he heads.
