conference hall of TsAGI Engineering Building, a welcoming speech was delivered
by the Head of the School-Seminar, RAS Academician A.I.Leontyev. The
participants were also welcomed by Mayor of Zhukovskiy city A.P.Bobovnikov and
RAS Academician G.C.Byushgens. Two review lectures were delivered afterwards.
TsAGI Director S.L.Chernyshev told the audience about the prospects of aircraft
development in the world. Correspondent member of RAS, Advisor of TsAGI board
of directors V.Ya.Neyland recounted the lessons learned from Buran Project. The Founder and permanent Head of the School
Academician A.I.Leontyev noted that achievements of Russian science and
technology in aviation and space were generally acknowledged, but in our hard
and crisis times the following N.E.Zhukovskiy's words sounded predictive: "The
problem of aviation and air resistance ... contains much unexplored, and the
country is happy possessing the means for research of this unexplored..." The School-Seminar for young scientists and
specialists under supervision of RAS Academician A.I.Leontyev has been
conducted for over 30 years. The first meeting was held in The last years contributed much in expansion of the
School topics. Now they include not only the needs of power engineering but
also cover the interests of metal and chemical industries, space and rocket
engineering, biology, medicine, and ecology. The problems discussed at the
section meetings comprise the foreground directions of basic research in gas
dynamics and heat and mass transfer in homogenous and heterogeneous mediums in
gas turbine and rocket engines, nuclear reactors and other power plants.
Special attention is given to the physical and mathematical models of phenomena
and processes; ecological aspects are considered. Scientific and practical importance of results, submitted
in the papers on gas dynamics and heat and mass transfer, condition the
relevance and need of regular Schools for young scientists and specialists of
this field of knowledge. Participation of students and post-graduates of
Russian universities and institutions of the Russian Academy of Sciences, young
engineers and specialists from Russian Ministry of Fuel and Power Engineering
and other departments and branches, in discussion of basic problems of gas
dynamics and heat transfer in power plants of different purposes allows
integration and interaction of representatives from academic and industrial
science and higher schools, establishment of new promising research subjects,
which often occur on the interface of scientific areas. Exchange of views and discussions enable to analyze
and estimate the level of scientific and research works, to compare it with the
world level, to develop the proposals on directions of basic research, on
academic curriculums, lecture courses and advanced training programs, on programs
for the training of young specialists and lecturers and accordingly the
subjects for doctoral and candidate theses, graduate and educational research
works; besides, it enables to select interesting works to be submitted at the
international conferences and workshops, to develop the guidelines for
practical application and implementation of new technologies in Russian
industry. This creates a basis for development of the leading scientific
schools, training of personnel of outstanding qualifications responsible for
science and industry progress. Head of the School - Academician of RAS Alexander
Ivanovich Leontyev is a prominent scientist in thermal physics and heat and
mass transfer. Since 1998 he has been an Advisor of N.E.Bauman MSTU authorities,
since 1995 - Chairman of National Committee on heat and mass transfer of the Academician A.I.Leontyev is a laureate of the National
Prize of Russian Federation in science and technology (1988), laureate of
Polzunov prize of the In In the framework of the 17th
School-Seminar, held this year, two round tables were conducted. The first one
consisted of the papers submitted by the laureates of the previous 16th
School, and the second dealt with the problems of heat and mass transfer in
different engineering applications. The 17th School Organizers enriched the
program with a number of interesting informative tours that proved to be very
popular among the participants. The most interesting ones are the tours of
experimental base of Central Aerohydrodynamics Institute: subsonic (T-101,
T-104, T-124), transonic (T-106, T-109, T-128) and hypersonic (T-117, VAT-103,
VAT-104) wind tunnels, test beds and apparatus of strength laboratory (rooms
for static and durability tests, reverberation chamber), and simulators of
flight dynamics (PSPK-102). The majority of papers at the School were delivered as
poster papers in the framework of six sessions: (1) gas dynamics and heat
transfer in external flows; (2) experiment and numerical modeling, thermal
shielding, high temperature materials and constructions; (3) gas dynamics and
heat and mass transfer in channels, mixing and combustion processes; (4)
boundary layers, separated flows, stability, laminar-turbulent transition, flow
control; (5) aerophysics of radiating gases and disperse flows; (6) heat
transfer at phase transitions. At each session the lectures of invited leading
specialists were delivered. Thus, the School participants - young scientists
and specialists - had a chance not only to exchange experience with their peers
but also to communicate with prominent scientists, to see their presentations
and listen to their remarks and advices on submitted papers. The first session opened with four lectures.
B.I.Katorgin (MSTU) told about heat and mass transfer in rocket and space
plants of high power. E.Ye.Son's (MPhTI) lecture dealt with the problems of
plasma aerodynamics, and S.V.Bobashev (A.F.Yoffe Physical Technical Institute
of RAS) in his speech covered local thermal flux measurements in shock tubes
with gas and plasma flows around bodies. The audience was very interested in
the lecture delivered by S.Z.Sapozhnikov (St. Petersburg STU) on new sensors
and devices for high temperature gradient heat measurements. Among the most relevant works of the first session the
Organizing Committee noted A.N.Sterlyagov's (ITP SB RAS, Novosibirsk) paper
"New non-invasive techniques for heat and mass transfer research in porous
mediums" devoted to the development and testing of gamma-raying for research of
mass transfer processes in porous mediums without breaking the material
structure. It is experimentally shown that while studying the processes of heat
and mass transfer in porous mediums the non-invasive techniques enable to
obtain results with high accuracy and less difficulties if compared with
conventional measurement techniques. Special attention the audience gave to the
paper by S.A.Mozhayskiy ( The meeting of the second section opened with
presentations of the leading scientists and specialists. In the lecture
"Numerical simulation of complex problems in hydrodynamics, heat transfer and
elasticity: thermal stresses in a model of cooled gas turbine blade"
(V.I.Artemov (MPEI), D.B.Spolding (Concentration Heat and Momentum Limited,
London, UK)) numerical methods were considered for simulation of complex
problems in which together with hydrodynamics and heat transfer it was necessary
to simulate stresses and strains in the streamlined construction elements. The
authors illustrated solution of applied problem and substantiated the efficient
application of finite volume method by the numerical results of simulation of
high temperature gas flow around a turbine blade model with an internal cooling
channel. V.I.Terekhov and M.A.Pakhomov (ITP SB RAS) in their lecture "Turbulent
jets with evaporating drops. Experiment, numerical simulation, applications"
told about two-phase jet flows with solid particles or drops which are widely
used in different engineering fields. The work summarized experimental and
numerical research in this area that has been conducted in the The first prize at the session was awarded to the
paper by T.Yu.Izmodenova ("Klimov" Public Corporation, The Organizing Committee also awarded Ye.Ye.Strizhov's
work "Simulation of thermal state of a piston of augmented half-speed diesel
engine". The obtained results enabled the author to come to the conclusion that
a refined calculation procedure should be developed allowing for the locality
of thermal contact resistance values. The third session also started with the lectures of
invited specialists. M.A.Gotovskiy (NPO CKTI, St. Petersburg) in his lecture
"Heat transfer augmentation using artificial roughness at Reynolds numbers
corresponding to laminar and transitional modes, and its possible practical
applications" told the audience about the general characteristics of heat
transfer surfaces with roughness elements formed by external pressure, pointed
out a number of common properties of such surfaces, the most important of which
is a simultaneous heat transfer augmentation on outer and inner sides.
R.Z.Kavtaradze (N.E.Bauman MSTU) touched upon the influence of different
factors on efficient and green performance of a diesel engine converted into
gas engine. A.A.Khalatov (Institute for Technical Thermal Physics, The participants of the third session were highly
interested in a paper presented by D.S.Yanyshev (MAI), who made a review of
current studies of turbulent flows in channels under hydrodynamic unsteadiness,
provided the main approaches to simulation of such flows and analyzed some
available results. He concluded that despite the crucial role of unsteady
thermal and hydrodynamic processes in development of new engineering samples in
different fields (propulsion engineering, aviation, aeronautics, power
engineering, shipbuilding, cryogenic technology, chemical engineering), the
mechanism of flow acceleration and deceleration influence on turbulence had not
been fully explored yet. Objective complexity of such flows with superimposed
hydrodynamic unsteadiness was noted in paper by the group of authors from
Research Center of Power Engineering Problems of The problem of turbine blades cooling which has
already been extensively discussed in papers of the second session was also
considered in proceedings of the third one. In particular the audience was
interested by the paper prepared by already mentioned group from Rybinsk State
Academy of Aviation Technology (RSAAT) (S.V.Veretennikov, S.M.Khasanov,
S.A.Smirnov), where they study heat transfer of a swirl flow of overheated
water vapor in cylindrical channels. The paper gives experimental and numerical
results, criterion equations for estimation of heat transfer coefficients in
internal channels of cyclone system for turbine blades cooling and other heat
engineering devices. The third prize at the session was awarded to
A.A.Zelentsov (N.E.Bauman MSTU) for his report "Numerical and experimental
study of local heat transfer in combustion chamber of high-speed diesel engine
with different models of turbulence and heat transfer", in which he submitted
data on influence of computational model on resulting local heat fluxes. The fourth session of the School started its meeting
with two lectures. S.A.Isaev ( The first prize was awarded to A.V.Schelchkov
(A.N.Tupolev KSTU) for his paper "Structure of adiabatic two-phase flows in
channels with twisting inserts" dealing with flow visualization. The Organizing
Committee has also awarded the numerical research conducted in S.S.Kutateladze
Institute of Thermal Physics SB RAS, Novosibirsk (M.S.Makarov, A.Yu.Sakhnov
"Analytical solution of laminar boundary layer equations in conditions of
favorable pressure gradient") and Department of Aeromechanics and Aircraft
Engineering of Moscow Physical Technical Institute together with M.V.Lomonosov
Mechanics Research Institute (Ya.A.Dynnikov, T.V.Malakhova "Numerical
simulation of unsteady heat transfer in incompressible fluid using the method
of viscous vortex heat domains"). The fifth session began with L.P.Kholpanov's
(Institute of Chemical Physics of RAS, Chernogolovka) lecture "Hydrodynamics and
heat and mass transfer in heterogeneous mediums" in which calculation methods
for heterogeneous mediums were submitted according to two approaches: continual
and trajectory ones. The paper prepared at The sixth section of the School was opened by
O.A.Synkevich's (MPEI) lecture "Waves on the surface of vapor film at intensive
heat fluxes and mechanisms of its explosive rupture". The author considered
processes occurring in many cases: severe accidents at nuclear plants and
chemical industry, submarine volcanic eruptions, etc. Such processes, when
solid and liquid mediums of high temperature get in touch with cold fluid, are
widely investigated in laboratories of many countries. The major interest
during the work of the sixth session devoted to heat transfer at phase
transitions was raised by the paper by V.N.Andbayeva (Institute of Thermal Physics
of Ural Branch of RAS) "Phase transition fluid-vapor at boiling of solution of
helium and neon in argon. Acoustic field effect on the temperature of
achievable overheating". It was noted that scientific and engineering relevance
of this work was conditioned by the fact that the processes of storage,
transportation and application of cryogenic systems are accompanied by abrupt
pressure fluctuations, local heat release, and heat fluxes, which can lead to
hydraulic shocks, explosions and consequently to equipment damages. The Organizing Committee has also awarded a prize to
K.G.Kubrikov, Yu.P.Ivochkin from Joint Institute for High Temperatures of RAS
for their work "Experimental research of pressure fluctuations at film boiling
crisis of subcooled liquid" covering experimental verification of hypothesis of
possible destruction of a liquid-metal drop falling into water by an acoustic
pulse generated by explosive boiling of a cooling agent. The audience was also
interested by Yu.Yu.Puzina's (MPEI) paper "Deflection of an interface at film
boiling on downward facing end surface of a cylinder" which dealt with features
of heat and mass transfer processes in subcooled liquid conditioned by
multifactorial effects. The author developed mathematical description, obtained
numerical results for the problem of definition of a shape of interface surface
at film boiling and compared the calculation results with experiment. It should
be noted that at the sixth section Moscow Power Engineering Institute submitted
the largest number of works dealing mainly with numerical study of heat
transfer at phase transitions. At the final meeting of the School-seminar a
traditionally high scientific and engineering level of submitted papers was
stressed together with active participation of young specialists and
scientists. The participants and Organizing Committee expressed their joint
desire to meet at the next, eighteenth, School under supervision of RAS
Academician Alexander Ivanovich Leontyev. The review was
prepared using materials from web sites of N.E.Bauman MSTU
(http://energy.bmstu.ru) and N.Ye.Zhukovskiy Central Aerohydrodynamics
Institute (http://www.tsagi.ru). |
