Solutions to the variable permeability magnetostatic field
problem are achieved in both rectangular and cylindrical coordinates
for a wide variety of magnet geometries. The resulting
difference equations are solved iteratively and a method is
provided which substantially increases the rate of convergence
for these type of problems. Magnetization curves for...
The thesis describes the preliminary studies on a
laboratory model of a magnetic elevator intended as part
of a system for circulating magnetic materials in chemical
reactors. A multiple coil laboratory model, controlled by
computer, was designed and constructed. Current measuring
transducers were used to monitor system performance and
study...
Magnetically Assisted Fluidized Bed (MAFB) is a novel technology where an external magnetic field with constant gradient interacts with magnetically susceptible particles. The linear magnetic field creates two type of forces: external and interparticle magnetic forces. A theoretical mathematical model based on the interaction of ideal dipoles is proposed to...
Traditional modeling of fluidized bed operations has focused on the development of models and correlations for specific systems or narrow areas of application. With recent advances in computing power, new methods of modeling fluidization are possible. One such approach is the Computational Fluid Dynamic Discrete Particle Method (CFD-DPM), which treats...
During the North Pacific cruise of the R/V Yaquina in 1966,
total magnetic field intensity was measured in the Andreanof group
of the Aleutian Islands. Three north-south track lines were made
across the Aleutian Trench and ridge between longitudes 175° W
and 180°.
Three small scale magnetic profiles across the...
Surface acoustic wave (SAW) sensors are versatile devices that can be configured to sense a variety of measurands such as temperature and pressure. The potential use of surface acoustic wave devices for magnetic field detection is explored in this study. Compared to current magnetic field sensors, a sensor based on...
As interest grows in developing devices to harvest energy from ocean waves, tidal currents, and offshore wind, concerns over possible environmental effects from such devices also grow. One such concern is over the induced electric fields and the generated magnetic fields from generators and their associated submarine power cables in...
