Flow Resistance of a Magnetic Fluid in a Two-Dimensional Channel. Interaction between Magnetic Field and Vorticity.

Yoshiyuki MATSUNO, Koyu ARAKI, H. Yamamoto

Abstract

The effect of a homogeneous magnetic field on the flow resistance of a magnetic fluid whose solid particles possess intrinsic magnetic moments is investigated. Flow resistance is tested in a two-dimensional channel in which the component of a liquid flow vorticity can be precisely evaluated. The increase of a flow resistance under the effect of magnetic field is analysed with the aid of the Shliomis equation in regard to the interaction between magnetic field and vortical flow. As a result, the mechanism of the flow resistance of a magnetic fluid is clarified.
