Effect of diffusion of magnetic particles on the parameters of the magnetic fluid seal: A numerical simulation
Krakov, M. S.; Nikiforov, I. V. (Institute of Physics, University of Latvia, 2014)In the paper, a motion of magnetic nanoparticles in a high gradient magnetic field and its correlation with the characteristics of the magnetic fluid seal are numerically studied. The neutral curve defining a range of parameters, where the liquid keeps fluidity, is found. It is shown that the concentration of particles during the initial time period grows linearly and then the ...2016-03-29 -
Influence of the meridional flow and thermomagnetic convection on characteristics of magnetic fluid seal
Krakov, M. S.; Nikiforov, I. V. (Maik Nauka-Interperiodica Publishing, 2011)For the low-speed magnetic fluid seals, the influence of the meridional flow, induced by the shaft rotation, on the distribution of magnetic particles concentration, is studied. Influence of the thermomagnetic convection on the structure of this flow and on the temperature distribution in high-speed magnetic fluid seals is investigated also. The problems were examined by numerical ...2016-03-29 -
Thermoconvective flow velocity in a high-speed magnetofluid seal after it has stopped
Krakov, M. S.; Nikiforov, I. V. (Maik Nauka-Interperiodica Publishing, 2012)Convective flow is investigated in the high-speed (linear velocity of the shaft seal is more than 1 m/s) magnetofluid shaft seal after it has been stopped. Magnetic fluid is preliminarily heated due to viscous friction in the moving seal. After the shaft has been stopped, nonuniform heated fluid remains under the action of a high-gradient magnetic field. Numerical analysis has ...2016-03-29
