Theory of capture of particles in magnetic high-intensity filters

摘要: This paper considers the capture of paramagnetic particles, radius R and susceptibility χ from a slurry, viscosity η, by ferromagnetic wire, saturation magnetization M s , in uniform magnetic field H o large enough to saturate applied perpendicular axis wire. When slurry is far away wire it's velocity V . Capture considered for various orientations with respect In calculations fluid treated inviscid, incompressible approximation. Calculation shows that when /2μ large, c increases For values m /V where velocity, = (2χM R2/9ηa). The increased performance observed filters μ consistent increase Effects configurations flow relation are used could not be explained terms differences bare It argued these due different dependences on volume material captured configurations.
