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...
The effect of a non-uniform magnetic field on the coupled transport of momentum and heat is studied for the case of laminar pipe flow of a magnetically susceptible ferrofluid. The momentum and heat transport equations are complemented with the necessary electromagnetic terms and used to develop a computer simulation of...
In a fluidized bed of magnetically susceptible particles, the presence of
a magnetic field induce the formation of particle chains due to interparticle
magnetic forces. The resulting effect is a change in the overall spatial
distribution of the particles, transitioning from a random, isotropic distribution
to an ordered, anisotropic distribution....
The effect of unsteady thermocapillary convection on the mass transfer rate of a solute between two immiscible liquids within a rectangular microscale channel with differentially heated sidewalls was numerically investigated. A computational fluid dynamic code in Fortran77 was developed using the finite volume method with Marker and Cell (MAC) technique...
Disposal of chlorinated hydrocarbons is a major environmental concern due to the lack of a satisfactory means of safe remediation at all contaminated locations. Current technologies rely primarily on incineration, a process that can lead to dangerous byproducts such as dioxin. If the chlorine substituent can be removed prior to...
Sulfur content of fuels and desulfurization of fuels is becoming an
important environmental restriction and regulatory issue. In this study new
technology for the desulfurization of fuels is considered. Micro scale reactors are
introduced for desulfurization of thiophene and dibenzothiophene.
Thiophene and dibenzothiophene are mixed with hexane at concentration, C₀...
High specificity to certain class of chemical and biological agents makes
biosensors unreliable for the detection of unknown agents. Also, the analytical
techniques are subject to systematic errors based on the mechanism of detection
leading to false negative and false positive results. Therefore, the results of these
analyses must be...
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...
Sulfur content in fuel is an increasingly important environmental concern. A
commonly used method for the removal of sulfur bearing species from fuel is
through hydrodesulphurization. However, due to the implementation of Ultra-Low
Diesel Sulfur (ULDS), deeper desulphurization techniques must be explored. In this
study, a single phase oxidative desulphurization...
