Drozdova V. I. The Effect of Interface Tension on Forced Oscillations of Elongated Microdroplet Aggregates in Magnetic Fluids [Електронний ресурс] / V. I. Drozdova, G. V. Shagrova, M. G. Romanenko // Журнал нано- та електронної фізики. - 2014. - Т. 6, № 3. - С. 03013-1-03013-3. - Режим доступу: http://nbuv.gov.ua/UJRN/jnef_2014_6_3_15 Changes in the shape of microdroplet aggregates exposed to an alternating magnetic field with frequency from 0,01 to 1 Hz are investigated both experimentally and using a computer simulation. Microdroplet aggregates are spherical droplets of a highly concentrated magnetic fluid with a radius from one to several tens of microns dispersed in a liquid with a low concentration of magnetic particles. For values of interfacial tension <$Esigma ~>>~2~cdot~10 sup -6> N/m small oscillations in a weak alternating field could not be obtained, but periodic forced oscillations were obtained at strong elongations. Oscillations of elongated microdroplet aggregates are of a periodical nonsinusoidal type with higher harmonics and subharmonics in the spectrum.

Shagrova G. V. Modeling Oscillations of Magnetizable Microdrops [Електронний ресурс] / G. V. Shagrova, V. I. Drozdova, M. G. Romanenko // Журнал нано- та електронної фізики. - 2015. - Т. 7, № 4. - С. 04020-1-04020-4. - Режим доступу: http://nbuv.gov.ua/UJRN/jnef_2015_7_4_22 Developed a system of computer simulation of oscillations of magnetizable microdrops in a wide range of changing their parameters: surface tension, viscosity, magnetic permeability, density, and radius. Computational experiments of oscillations of magnetizable drops in an alternating magnetic field and the influence of various forces of nature (inertial, viscous, surface and magnetic) on the nature of the oscillations were carried out. Adequacy of the model, used as the basis for the developed system of computer simulation was shown on the basis of computational and experimental data.

Drozdova V. I. Spectrum Features of Forced Oscillations of Microdroplet Aggregates in Magnetic Fluids [Електронний ресурс] / V. I. Drozdova, G. V. Shagrova, M. G. Romanenko // Журнал нано- та електронної фізики. - 2016. - Т. 8, № 3. - С. 03055-1-03055-3. - Режим доступу: http://nbuv.gov.ua/UJRN/jnef_2016_8_3_57 We have studied the discrete spectrum of the forced oscillation of microdroplet aggregates in magnetic fluid in magnetic field <$EH(t)~=~H sub 0 roman sin omega t> with the frequency of 0,01 - 100 Hz.
