dc.description.abstract The Electromagnetic Vaporization of Metal Particles (EVMP) process uses an alternating magnetic field to induce eddy-current heating within a metal particle. This heating causes the outer shells of the droplet to evaporate, thus reducing it to the required dimensions. The problem is modeled by considering a single metal droplet, stationary in an alternating magnetic field, in an inert gas under ambient conditions. The magnetic field is provided by a solenoid surrounding the droplet, and the problem of the evaporating particle solved under quasi-steady ambient conditions. A lumped analysis is used to evaluate conditions within the droplet. Radiation, convection and conduction are considered, and their relative magnitudes compared. The different modes of heat transfer are quantified and evaluated over time in terms of non-dimensional parameters. A simple mass transfer model is used, wherein the vapor is assumed to leave the droplet at very high velocities, due to the large difference in the liquid and vapor densities of liquid metal. The important non-dimensional parameters influencing in the process are identified.
