ABSTRACT
This paper presents a one-dimensional model of electrical discharge machining plasma with air as the dielectric medium (dry-EDM). Governing equations of particle balance (drift-diffusion) and energy balance are solved together to predict plasma properties such as electron and chemical species density, plasma temperature, plasma potential and current, and heat flux to the electrodes as a function of the axial distance along the inter-electrode gap and time. The model predictions of electron density and temperature are validated against experimental data from the literature. Simulation experiments are conducted to study the effect of open gap voltage and interelectrode gap on the dry EDM plasma properties.
Keywords: Dry EDM, Air Plasma, Modeling, Simulations.
