This paper presents comparative studies of magnetic characteristics and dynamic performances for two mutually coupled dual-channel switched reluctance machines (DCSRMs) with the same properties and different winding connections. A 2D/3D finite element method (FEM) is used to analyze the magnetic field distributions and calculate the static inductance and(More)
This paper is mainly devoted to the three-dimension calculation of the electric and magnetic fields in the simplified arc chamber of low-voltage circuit breakers. Coupled with the plasma flow field, the electric potential and current density in arc plasma are calculated according to the electric conductivity, which is mainly decided by the temperature.(More)

A two-dimensional flux-flow model is constructed to investigate the electromagnetic characteristics of a melt cast process BSCCO-2212 tube. Solving the flux-flow equilibrium equation with numerical method, we obtain the distributions of the current density, the flux density, and the flux-flow resistivity. The effect of inner radii on the critical current is(More)
It has been demonstrated that carbon nanotube (CNT) acts as a promising functional material to effectively detect infrared signals due to the unique properties arose from its novel geometry. However, the performance of CNT based photodetectors is limited by low fill factor owing to their small photon absorption area. In order to address this problem, a(More)
For the electromagnetic rail launcher, the parameters variation has obvious effect on the dynamic performance and efficiency.
