Abstract: Except theoretical interest, the problem
is of paramount importance for practical applications in
three different aspects. Parametric excitation of
oscillations in continua serves for intensification of
various technological and technical processes, e.g. heat
and mass transfer, mixing, decreasing of viscosity and
conductivity, improving a quality for crystallizating
metal, etc. Second, excitation of parameter oscillations
is used for disintegration of jet/film flows
(spray-coating, metal spraying, granulation of
materials, e.g. particles’ producing from molten
metals). And the third is opposite to the second one,
suppression of oscillations for stabilization of
unstable regimes/processes, for example, thermal,
electromechanical and electrochemical, combustion, and
so on. Moreover, sometimes parametric control leads to a
process impossible without it.
Brief
Biography of the Speaker:
Ivan Kazachkov is a Mechanical Engineer. He earned his
PhD (Candidate of Physical and Mathematical Sciences,
1981) and MSc (1976) at the National Taras Shevchenko
University in the City of Kyiv in USSR. His Full
Doctorship (1991) in Engineering Sciences he has got at
the Institute of Physics of Riga, Latvian Academy of
Sciences. Presently he is teaching at the National
Technical University of Ukraine “KPI”. He is also an
Affiliated professor at the Royal Institute of
Technology in Stockholm, where he has been teaching
numerical methods and doing research in modeling of
multiphase systems as visiting professor during the
period of about ten years (since 1999 until 2004
permanently). His research activities include Parametric
Control in Continua, Multiphase Flows, Controlled Film
Flow Disintegration and Granulation of Metals for Space
Industry, Modeling and Simulation. He has more than 200
publications in scientific journals and scientific
conferences. He participates in European research
programs and committees. Many PhD students are doing
research under his supervision.
