Bashtovoi V. G. Influence of Mass Transfer Processes on Couette Flow of Magnetic Fluid [Електронний ресурс] / V. G. Bashtovoi, S. G. Pogirnitskaya, R. Kuzhir, V. M. Polunin, P. A. Ryapolov, I. A. Shabanova, A. M. Storozhenko // Journal of Nano- and Electronic Physics. - 2013. - Vol. 5, № 4(1). - С. 04011-1-04011-3. - Режим доступу: http://nbuv.gov.ua/UJRN/jnep_2013_5_4(1)__13 This article describes the results of a theoretical study of magnetic fluid two-dimensional Couett flow in magnetic fluid seal model in view of mass transfer processes. It has been shown that very inhomogeneous magnetic field in seal gap lead to magnetic particle concentration rearrangement due to magnetophoresis and Brownian diffusion. In turn, it lead to inhomogeneous magnetic fluid viscosity and change in local and integral shearing force at channel walls. Integral shearing force has been shown to depend on magnetic field and magnetic fluid parameters. Closely-packed fluid density distribution conditions have been defined. Proposed theory covers real magnetic fluid seal performance features adequately.

Bashtovoi V. Statics of Magnetic Fluid Drop with Compound Magnetic Core in a Wedge-Shaped Channel [Електронний ресурс] / V. Bashtovoi, S. Klimovich, А. Motsar, A. Reks, P. Ryapolov, A. Storozhenko, I. Shabanova // Journal of Nano- and Electronic Physics. - 2013. - Vol. 5, № 4(1). - С. 04012-1-04012-4. - Режим доступу: http://nbuv.gov.ua/UJRN/jnep_2013_5_4(1)__14 A behavior of magnetic fluid drop with compound magnetic core in a wedge-shaped channel was studied experimentally. The study examines influence of magnetic fluid properties, its volume and magnetic field on statics of the system compound magnet - magnetic fluid drop in wedge-shaped channel. The possibility to change the static conditions of such system by altering magnetic field of the core was observed.

Bashtovoi V. Influence of Brownian Diffusion on Levitation of Bodies in Magnetic Fluid [Електронний ресурс] / V. Bashtovoi, A. Reks, S. Klimovich, А. Motsar, P. Ryapolov, A. Storozhenko, I. Shabanova // Journal of Nano- and Electronic Physics. - 2013. - Vol. 5, № 4(1). - С. 04028-1-04028-3. - Режим доступу: http://nbuv.gov.ua/UJRN/jnep_2013_5_4(1)__30 The present work deals with experimental investigation of the levitation of magnetic and non-magnetic bodies in a magnetic fluid when essentially influenced by Brownian diffusion of magnetic particles in it. It is established that the point of levitation of bodies in a magnetic fluid varies with time.
