Influence of the meridional flow and thermomagnetic convection on characteristics of magnetic fluid seal

, 2020
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

Thermoconvective flow velocity in a high-speed magnetofluid seal after it has stopped

, 2020
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
