A theoretical model of nickel electroforming within the patterned photo-resist microstructures is proposed. Fluid flow, transport of ion species and electrode reaction kinetics are fully coupled in this model to characterize the electroforming system. Numerical simulations of the electroforming process are carried out using a finite element method. By analyzing time variation of the reaction ions...
The Roll-Ring with a rolling electrical contact is usually utilized in an electrical energy transmission system between two continuous relative rotated equipments, such as the rotation system in radar, tank, space station and so on. As long as the requirement of the transmission power increasing in these years, the rolling electrical characteristic is more and more important for the long-life design...
This paper focuses on the numerical investigation of arc plasma behavior in a certain type molded circuit breaker. A 3-D simulation model based on the magneto-hydrodynamics theory is built and calculated. The basic arc parameters are described by the coupled equations of gas dynamics and electromagnetic field. By adopting a thin layer of nonlinear resistance elements to represent the voltage drop...
