| Abstract Scope |
Electrospray is an electrohydrodynamic atomization process that subjects a liquid to a strong electric field, causing the liquid to be drawn from the source in the form of small droplets. This process could be applied to refractory metal wire to synthesize fine, spherical powders for use in additive manufacturing. COMSOL Multiphysics software was used for initial modeling of the process conducted on water and liquid metals. By simulating a charged needle holding the working fluid, opposite from a counter-electrode, the behavior of the fluid surface under different operating parameters can be studied. These models use a moving mesh to simulate the fluid flow coupled with the forces from the applied electric field to demonstrate the applicability of the electrospray process for use in powder synthesis for additive manufacturing of refractory metals. |
