Estimation of Minimum Size of Electrodes for Face-to-Face Double Probe using Two-Dimensional Particle-in-Cell Simulation

چکیده
To optimize the “Face-to-face Double Probe (FDP)” method, which is proposed by the authors to measure the Mach number of a plasma flow [Saitou and Tsushima, Jpn. J. Appl. Phys. 40, L1387 (2001)], performances of an FDP have been investigated focusing on a characteristic length of a pair of electrodes using a two-dimensional particle-in-cell simulation. Resulting from the simulation, both the characteristic length needed for a good FDP performance and a correction factor needed for the FDP with small electrodes are presented.

Optimum design of a double-sided permanent magnet linear synchronous motor to minimize the detent force
In the permanent magnet linear synchronous motor (PMLSM), force ripple is harmful, useless and disturbing. The force ripple is basically composed of two components: detent force and mutual force ripple. This force is influenced by the geometric parameters of the permanent magnet (PM) motors; such as width, thickness and length of the magnet poles, length and thickness of the rotor and stato...

متن کاملA Numerical Simulation Study on the Kinetics of Asphaltene Particle Flocculation in a Two-dimensional Shear Flow
In the current study, the kinetics of asphaltene particle flocculation is investigated under a shear flow through numerical simulation. The discrete element method (DEM) is coupled with computational fluid dynamics (CFD) to model the agglomeration and fragmentation processes. In addition, a coalescence model is proposed to consider the attachment of colliding particles. The changes in mean asph...

متن کاملStudying Peak Particle Velocity Due to Blast in Development Tunnels’ Face in Coal Stoping
The impact of blast-driven shocks on the safety and stability of the underground coal mines has been well established. The seismic imperfections resulting from blasting depend on the total explosive energy released during blasting and the closeness of the development tunnel face to the stope face. Also, the quality of the rock mass wherein the whole stope face is located might pose considerable...
