Simulation Study on Motion of Metal Particles During Translation of Flat Plate Electrode

A two-dimensional flat plate electrode advection model is established, and the SST k-ω turbulence model is selected to study the insulating oil motion according to the plate motion. The N-S equation of the impinging oil flow is constructed by the Eulerian method, and the kinetic equation of the metal particles is constructed by the Lagrangian method, and they are coupled by the interaction forces for the solid–liquid two-phase flow. The simulation is carried out to obtain the flow state of insulating oil when the flat plate is moving and the motion of metal particles under multiple forces. It has been found that during the translation of flat electrodes, the particles also develop a “small bridges”, which may cause breakdown.
