This paper describes flowing of molten metal in a novel electric arc furnace. Combined AC and DC components are used in the supply system for the furnace. Finite element method is used to investigate the impact of AC component frequency on the flowing of molten metal.
A novel dynamical model for a single cell electric double-layer capacitor is proposed. The model was derived from a distributed-parameter electrochemical model, first reformulated and then approximated to reduce its order. Finite dimension approximations were obtained by applying finite differences, finite element and differential quadrature semidiscretization methods. The best approach was obtained...
An alternative approach to develop a large signal time dependent model of a simple electrochemical capacitor is proposed. A simple planar electrochemical cell consisting of two metal electrodes separated by a sulfuric acid electrolyte layer is modeled from first principles. The model is a large signal time dependent model and is valid under constant temperature conditions. The model is based on the...
