The mathematical model is presented, describing a turbulent flow of the electric arc plasma in air-vapour plasmatrons
with a refractory cathode. <...> The effect of operating parameters of a plasmatron and kind of the employed plasma gas on
electric and energy characteristics of the arc, as well as on thermal and gas-dynamic characteristics of the plasma flow
generated by such a plasmatron, is numerically studied. <...> K e y w o r d s : arc, electric and energy characteristics, numerical analysis, arc plasma, refractory cathode, vapour plasmatron
The corresponding mathematical model described
in this study was developed in order to optimise design
of a vapour plasmatron and select the optimal modes
Plasma energy sources are finding an increasingly
wider application to meet the needs of the most diversefor its operation. <...> Consider the main condiindustrial sectors <...>

75th ANNIVERSARY OF THE E.O. PATON
ELECTRIC WELDING INSTITUTE
On October 2, 2009 a gala meeting devoted to the 75th anniversary of the E.O. Paton Electric
Welding Institute was held at the Institute, which is the world-renowned research center in the
field of welding, electrometallurgy and protective coating deposition. The meeting was att
ended
by the Institute staff, as well as numerous guests ---- heads of departments, enterprises, leading
academic and research institutions and higher educational establishments of Ukraine.
The meeting was opened by academician B.E. Paton, President of the National Academy of
Sciences of Ukraine, Director of the E.O. Paton Electric Welding Institute, who delivered a
report on the main stages of the Institute activity in different periods. He noted that «th
e
Institute has a powerful scientific potential and is developing, its structure and mana gement
system are being improved ---- all the efforts are focused on further advance of welding and
related processes, on solving the basic problems of production».
Boris E. Paton expressed his sincere gratitude to all those who had congratulated the Instit
ute’s
staff with the jubilee, his high appreciation of the staff activity and his hope for further development
of the Institute and achievement of new high results by young scientists in the theor y
and practice of welding fabrication.
Among those who congratulated the Institute are tens of research establishments, enterprise s
and organizations, colleagues and friends from Ukraine, Russia, Belarus, Bulgaria, Armenia,
Georgia, Kazakhstan, Germany, Slovakia and Uzbekistan.
Then Yu.P. Bogutsky, Deputy Head of the Secretariat of the President of Ukraine, read the
greetings from V.A. Yushchenko to the Institute staff, expressing a firm belief that «with it s
highly professional and inspired activities the Institute’s staff will continue making a su
contribution to development of the national and world science and strengthening of the eco
of the Ukrainian state». Yu.P. Bogutsky read the Decree of the President of Ukraine on decorat
the Institute staff with the state awards of Ukraine.

ing
V.B. Yalovoj read the greetings on behalf of V.M. Litvin, Chairman of Verkhovna Rada of
Ukraine. In them it was noted that the indefatigable creative activity of the representatives of
the known Paton school promoted transformation of welding into the leading technology in
many branches of the national economy, which is applied in different environments, in parti
deep under the water and high up in space. To-day significant results have already been achieve
cular
d
also in the medical field, namely making reliable welded joints of soft live tissues. Scienti fic
achievements and developments of patonovites, and technologies developed by them are miles
tones
in the progress of world science and engineering. The Institute scientists have convincin gly
proved their ability to solve scientific and engineering problems of any complexity.
A.N. Gurzhy read the address of Yu.V. Timoshenko, Prime Minister of Ukraine. It expressed
sincere gratitude to the Institute’s staff for their self-sacrificing work and recognized scientificengineering
achievements, which make our economy competitive and enhance the scientific
authority of Ukraine in the world.
Short speeches of V.S. Romanyuk, Director of PWI Experimental Design-Technological Bureau
,
and V.I. Stepakhno, Director of Pilot Plant of Welding Equipment, were followed by greetings
and warm congratulations for the Institute staff from the Presidium of the NAS of Ukraine (A.
G.
Shpak), Department of Physical and Technical Problems of Materials Science of the NAS of
Ukraine (I.K. Pokhodnya), NTUU «Kiev Polytechnic Institute» (Yu.I. Yakimenko), Ministry
of Industrial Policy (S.G. Grishchenko) and Chairman of Kiev Goloseevo District Administrat
(A.G. Neznal).
