Professor Algirdas Zukauskas
on his 70th birthday

PROFESSORAlgirdas

iukauskas, Academicianof theLithuanian Academy of Sciences, Honorary Editorial
Advisory Board Member of the hrernatimal
Jourtdof‘ Heat and Mass Tram/b was born on February 2.
1923 in Lithuania.
In 1947 he graduated from Vitautas Magnus University in Kaunas. After graduating he worked as anAssistant Professor at the university in the Department of Engineering and from 1951 at the Kaunas
Polytechnic Institute. In the period of 1952-1953 hespecialized in heat transfer at the Moscow Institute ofPower Engineering.
After graduating
he started the research in convective heat transfer and fluid mechanics from circularcylinders and tube bundles that led in 1953 to theCandidate degree (EngineeringSciences). Later, hedefended his doctor’s thesis entitled ‘Convective Heat
Transfer in Viscous Fluid Flows’ (I 963).
In 1953 A. iukauskas joined the Physical and Technical Institute of the Lithuanian Academy of Scienceswhere he organized a research laboratory of heattransfer. He also worked as the Associate Professor
and then Professor at the Kaunas Polytechnic Institute.
Since 1956 Algirdas iukauskas had been working
as the head of the laboratoryand director of theInstitute of Physical and Technical
Problems ofEngineering of the LithuanianAcademy of Sciencesin Kaunas. Since 1966 A. pukauskas has been Vice-President of the Academy. at the same time leading
heat transfer investigations at the Kaunas Institute.
During many years the research activities of Professor Zukauskas involved a laminar boundary layer
and heat transfer in laminar flows, a turbulent boundary layer and heat transfer in turbulent flows, a flow
pattern over a cylinder and heat transfer from cylinders in crossflow, heat transfer from tube bundles incrossflow. heat transfer and flow over rough andfinned tubes. vibrations of tubes in heat exchangers.
heat transfer in channel and duct flows, heat transfer
in the presence of chemical reactions and high-tcmperature gas flows, combined convective and radiative
heat transfer. At present he is working on the problems of augmentationof heat transfer and efficiencyof heat exchangers.
Professor iukauskas
was the first to start investigations of heat transfer in Lithuania. He is a founderof the convective heat transfer school in Lithuania.
He has established the laws and deduced the formulae
for calculating convective heat transfer in liquids. The
methods which have been put forward by him forthe calculation of heat transfer are being used in theconstruction of heat exchangers in power engineering,the chemical industry and other fields of technology.
The results of his research are now cited in different
handbooks and textbooks in many countries.
About 500 scientific publications by A. iukauskas
have been issued in Lithuania,

Since 1968 A. Zukauskas has been the Editor-inChief of the series of monographs Thermophysics, 22monographs of which have been already published inVilnius. He is also the Editor of the Journal of PowerEngineering issued in Vilnius, Heat Transfer-Soviet
Reviews series published in New York, the serial collection Achievements in Heat Transfer and a memberof the editorial and advisory boards of the handbook
Heat Eschunger Design Handbook and the journals :Inzhenerno-jizicheskii

Communications
inHeat and Mass Transfer, Experimental
Thermal andFluid Science, Journal of Energy, Heat and MassTransfer. Fifty Candidate and Doctor theses weremaintained under his guidance. He holds numerous
patents. Professor A. Zukauskas also contributed
much to scientific cooperation among various countries. Practically, he is engaged in the work of various
councils and committees of heat and mass transfer,power engineering and atomic energy in Lithuania
and other countries. He is a member of the World
Assembly of International
Conferences on HeatTransfer, the International
Center for Heat and MassTransfer
and the International
AssociationofHydraulic Research.

er al.

For many years he served on the Committee forScientificCooperationin Thermophysics,
theNational Committee for Heat and Mass Transfer in
the Soviet Union, the Heat Transfer Committee forthe Baltic States, being also the chairman of the committee of the same name inside the Republic.
Professor iukauskas
visited various scientificcentres and universities and lectured in the U.S.S.R.,
the U.K., Austria, Canada, the U.S.A., Germany,
Japan, Yugoslavia,France, Czechoslovakia,
India,Italy, Sweden and other countries. He is regularly
invited to international
conferences to deliver hisreview lectures on heat transfer in single-phase flows
and on the problems of heat transfer augmentation.
Professor A. Zukauskas is a well-known personality
in the professional world. His works have greatly contributed to the development of the theory of heattransfer and fluid mechanics and of heat exchangers.
Many honours have been bestowed on Professor
iukauskasin recognition
for his professional
accomplishments. In 1962 he was elected a member ofthe Lithuanian Academy of Sciences. He has received
The Fellowship Award of the International
Center for
Heat and Mass Transfer (1986), the State Prize of theLithuanian
Republic (1975), the titles of Honoured
Researcher of the Lithuanian
Republic (1974) andHonoured
Engineerof the LithuanianRepublic(1965) and others.
Best congratulations
are extended to Professor
Algirdas pukauskas by long-time co-workers, numerous thermal engineering
students, colleagues andfriends from different countries. Many happy years,
good health, fruitful scientific work and good luck to
the whole family!
