Abstract
We conducted a two-dimensional numerical simulation of ferromagnetic floc motion (coagulated particles containing ferromagnetic particles) in a magnetic field and a flow field to analyze the effect of physical parameters( number of magnets, floc diameter, volume content rate of magnetic particles, mean value of fluid velocity, and kinetic viscosity) on magnetic separation performance. In the present study, we used magnetic fields applied by permanent neodymium magnets. The calculation results show that the logarithm of the residual rate of the flocs is approximately proportional to the number of applied magnets and the residual rate is approximately expressed as a function with parameters stated above in this study.
