MATHEMATICAL MODELING OF THE ALUMINA POWDER SYNTHESIS BY PLASMA CHEMICAL PROCESSES // Tomsk State Pedagogical University Bulletin. 2011. Issue 8 (110). P. 60-63

Aspects of integrated effects of plasmatron mode parameters and heat-transfer medium properties on formation and evolution of droplet medium of injected solution by means of diffusion, filtration and heat transfer are considered. Mathematical model as well as calculation results for dependence of particle size and its liquid core on heating rate and initial mass fraction of dissolved salt are presented.

ABOUT ONE APPROACH TO CONDENSED SYSTEMS NONSTEADY BURNING RATE ESTIMATION // Tomsk State Pedagogical University Bulletin. 2011. Issue 8 (110). P. 64-66

In the present paper the new algorithm of non-stationary burning rate estimation within the framework phenomenological theory is offered. Comparison of the received results with known calculation results have shown their satisfactory qualitative coincidence. Advantage of the offered approach consists in reduction of the experimental information involved for problem statement.

THE STUDY OF SPRAYED LIQUID DROPLETS DISPERSITY BY SMALL-ANGLE SCATTERING METHOD // Tomsk State Pedagogical University Bulletin. 2012. Issue 7 (122). P. 15-18

Laser diagnostics of droplets sprayed by centrifugal atomizer was carried out by the small-angle scattering method. Solution of aerosol optics inverse problem was used for define the distribution function of droplet size in the sprayed liquid by the centrifugal atomizer.
