Role of the Diffusion Current in Nonequilibrium Modeling of Welding Arcs
发布日期 2014
2D self-consistent nonequilibrium model of a free-burning arc in argon has been developed. The model is based on the COMSOL Multiphysics® platform and describes in a self-consistent manner the fluid dynamics, the heat transfer, the magneto-electrodynamics, and species conservation. The governing equations are solved applying the COMSOL Multiphysics® interfaces Laminar flow, Electric Currents, and Magnetic Fields, which are complemented by Weak Form PDE for the temperatures of electrons and heavy particles, and species conservation for the ions. The work is focused on physically justified description of the effects in the regions of the arc plasma in the vicinity of the electrodes.
