Abstract

Sealing performance and flow characteristics of magnetic fluid in extremely tiny clearance less than 30 μm under magnetic field are investigated experimentally. The extremely tiny clearance in the test section is set to 5, 10, 15, 20 and 30 μm, and magnetic field is applied to magnetic fluid flow at this clearance. The results show that maximum of 1.2 MPa of pressure resistance was obtained at 5 μm of tiny clearance from the sealing test and the relationship among frictional coefficient, magnetic field and Re is quite different between 5 and 30 μm of tiny clearance from the flow characteristic test.
