The Scientific
Seminar “Problems of Continuum Mechanics” works on Wednesdays in the Institute
of Mechanics and Engineering, Kazan Science Center RAS. The Chairman of the
Seminar is Director of the Institute Dr. Sc. (Phys. & Math.)
D.A.Gubaidullin. Problem reports and dissertations of researchers of the
Institute and scientists from other organizations are presented and discussed
at the Seminar. Main scientific directions for presentation are:
·
non-linear mechanics of thin-walled constructions, hydroaeroelastic and
wave systems;
·
dynamics of multiphase multicomponent media in porous structures and
technological plants;
·
non-linear stability theory of control systems with changeable
structure.
20 June 2001 in the Institute of Mechanics and
Engineering KazSC RAS the Solemn Assembly and Seminar
dedicated to Decade of IME KazSC RAS were held. The following reports were
presented during the spring period of 2001 at the Seminar and the Solemn Assembly.

Fedyaev V.L.
Improvement of heat engineering equipment use of mathematical modeling methods. On materials of
thesis for Doctor of Sciences Degree, speciality: 05.13.18 – Mathematical modeling,
numerical methods and programming complex. Reviewers: DrSc Sachabutdinov Zh.M.,
DrSc Elizarov A.M. The objects of this investigations are the wave pumps
graduation towers, heat exchange and electric arc furnaces. The mathematical
models describing all totality of processes are presented. These problems are
integrating with the help of both analytical and numerical methods. From
results of these investigations, the original technical solutions are
presented. The efficiency of these solutions is examined with use of results of
modeling and industrial experiments.

Investigation of composite plates by method of boundary elements in combination
with variation method. Kama polytechnical institute. On materials of thesis
for Candidate of Sciences Degree, speciality: 01.02.04 - Mechanics of
deformable solid. Reviewer: DrSc (Techn.) Yakupov N.M. Problems of MBE and
hybrid approach are investigated and developed with reference to bending of
plates of complex contour. Methods of analysis and distinguishing of
singularities in contour integrals are developed, new approaches to the
approximation of boundary conditions are examined, possibilities for expansion
of MBE application are investigated on the basis of combination with energy
approach. Problems for plates, consisted of subdomains with different
thickness, are solved.

Institute of the Mechanics and Engineering KazSC RAS are given. In institute 55 employees work nowadays. In 1991-2001 12
doctor's and 15 candidate dissertations are defended in the Institute; 14
scientific monographies, 5 popular scientific, educational and methodical
books, 4 collections of the articles are issued; 10 results are included in the
annual reports on activity of RAS. The Institute took part in organization and
realization of 12 scientific conferences.
Tukmakov A.L.
Numerical modeling in problems of nonlinear dynamics of aeroelasticity systems. Aeroelasticity
processes under before-and supersonic flowing around the fine springy panels
are numerically investigated on the basis of geometrically nonlinear dynamic
set of equations of shells theory and model of viscid compressible gas with
heat conduction, oscillations of a gas in resonators on excitation by springy
piston are examined, oscillations in the resonator with springy borders are
considered. Nonlinear dynamic effects discovered are analyzed.

Anokhin S.V. Modeling of oil displacement from pools by gelatination
systems. On material of thesis for Candidate
of Sciences Degree, speciality: 01.02.05 - mechanics of fluids and plasma. Reviewer:
DSc (Techn.) Khairullin M.Kh.
Vinogradov I.V. Theoretical investigation of thermal
plasma flow in plasmotron with modulated current.
Gaynullin
F.R. Modeling of currents of liquid in channel with permeable partitions. Approaches to mathematical description and
calculation of currents of liquid through permeable partition, disposed in
channel, are offered. Results of numerical modeling for currents of ideal
incompressible liquid in filter rough peelings with one permeable partition are
given. Preliminary estimations for vortices behind the permeable partition are
presented as well.
Fayzelgayanov
A.M. Numerical simulation of turbulent boundary layer separation for internal problems of aerodynamics. Despite
of fundamental significance of a boundary layer separation, its full
theoretical or experimental description for large Reynolds numbers remains one
of the main problems of gas dynamics. For study of the indicated class of the
phenomena, the model describing turbulent boundary layer separation of a
supersonic gas flow is constructed. From a variety of being available models of
a turbulence the algebraic model Boldwin-Lomax is selected. The test
calculations for confirmation of reliability of a selected model and capacity
for work of the program are carried out. The phenomena of a separation of a gas
flow under the influence of oblique shocks on a boundary layer of various
intensity are investigated.
Yakupov N.M., Galimov N.K., Leontiev A.A.,
Nurgaliev A.R. Experimentally - theoretical method at research polymer films. Fundamentals of
experimentally-theoretical method of investigations of mechanical properties of
polymer films are presented. Form of representation of a shell canopy under
construction of deforming curves for films are examined.
Potential
participants are kindly invited for the presentation of their results at the
Seminar.
