Coupled Electromagnetic–Fluid–Thermal Analysis in Large Scale Water–Hydrogen Hydrogen-Cooled Generator-Condenser Under Different Operations

An optimization method based on the zonal harmonic description of the magnetic field, suitable for the design of axially symmetric magnetic sources, is presented. Expressions of both axial Bz and radial Bρ components of the magnetic field are obtained as the infinite sum of the zonal harmonics. For arrangements having as the basic building block […]

High-gradient magnetic chromatography (HGMC) is a technique for selectively separating magnetic particles (MPs) according to their magnetic susceptibilities. We develop a mathematical model for HGMC that includes the effects of magnetic force, Brownian motion, gravity, and viscous drag. We then use this model to interpret recently reported experimental results and to distinguish these efforts from […]
