摘      要：Conventional Ceramic Foam Filter(CFF)technology has some difficulties in removing fine particulates(e.g.20 μm)from liquid *** the present work the filtration behaviour of 30,50 and 80 ppi CFF filters have been studied in the presence of magnetic fields in the range of 0.06-0.2T,produced by induction coils operated at 50 Hz. A feed recipe containing 90 wt.%of the aluminium alloy A356 doped with 10 wt.%A356 composite,containing 15 wt% SiC particles with a particle size ranging from 13 to 23 μm,was *** the results obtained for the experiments conducted under the influence of a magnetic field where compared with similar reference gravity filtration experiments profound changes were observed in the distribution of particulates within,over and below the *** improvements in the wetting behaviour of the liquid metal to the CFF surface were also *** is believed that a successful change in filtration mechanisms is obtained as a result of the presence of the Lorentz forces and the metal recirculation produced by the magnetic *** magnitude of the Lorentz forces,*** magnetic pressure,are in the present work discussed in relation to the filtration results,and quantified based on experimental data and validated 2D axial symmetric Finite Element Modelling(FEM).
