Catalytic effect of submicron TiO2 particles on the methane–air flames speedSpringer Science and Business Media LLC - Tập 52 - Trang 155-166 - 2016
T. A. Bolshova, O. P. Korobeinichev, K. V. Toropetskii, A. G. Shmakov, A. A. Chernov
A PIV study of a conical premixed methane–air Bunsen flame has shown that the
inside of the cone has a complex gas-dynamic structure. In this system, the
velocity of the gas flow entering the flame front varies in different parts of
the flame cone and the stream tubes are not straight. The Landau–Markstein
effect is discussed in the interpretation of the experimental data. A method of
processing P... hiện toàn bộ
Comparative Analysis of Methods for Measuring the Transient Burning Rate. II. Research ResultsSpringer Science and Business Media LLC - Tập 46 - Trang 570-577 - 2010
V. A. Arkhipov, S. S. Bondarchuk, A. G. Korotkikh
This paper presents the results of measurements of the transient burning rate of
homogeneous and model composite solid propellants during sudden depressurization
of a semi-enclosed volume using two independent methods - high-speed photography
and a method based on solving the inverse problem of interior ballistics. A
comparative analysis of the results shows that the methods are mutually

Two-dimensional modes of filtration combustionSpringer Science and Business Media LLC - Tập 35 - Trang 126-132 - 1999
V. V. Grachev, T. P. Ivleva
A theoretical analysis is made of the possible modes of filtration combustion
and the transitions between modes with changing system parameters are studied.
The “initial pressure-filtration coefficient” plane is subdivided into regions
where the various modes exist. It is shown that at superstoichiometric initial
pressures, when there is enough gas in the pores for complete transformation of
the s... hiện toàn bộ
Ignition of a nonstoichiometric composition gas mixture by means of a spark discharge with a spatially-temporal energy releaseSpringer Science and Business Media LLC - Tập 28 - Trang 109-114 - 1992
I. G. Dik, I. P. Zamyatina, V. G. Prokof'ev
A model is proposed for the spark ignition of gas mixtures having
nonstoichiometric compositions. The model takes into account the structure and
dynamics of the discharge energy release. A region of discharge parameter values
is determined for which the applicability of the instantaneously localized
energy source is well founded. Critical ignition conditions are investigated for
a variation of the... hiện toàn bộ
Nucleation of structural defects in materials with a perfect crystal lattice by thermal fluctuations under dynamic loadingSpringer Science and Business Media LLC - Tập 42 - Trang 490-492 - 2006
S. G. Psakh’e, K. P. Zol’nikov, D. S. Kryzhevich, A. G. Lipnitskii
A molecular-dynamic study of nucleation of structural defects in materials with
an initially perfect crystal lattice by thermal fluctuations under high strain
rates is performed. It is shown that thermal fluctuations can generate
structural defects. There exists some threshold value of strain at which abrupt
growth of regions with local structural changes is observed.
