A&me-The axial dispersion problem formulated in part I[11 of this series is solved for cases 2-4 and 7 identified therein. The cases analyzed here consider appendages to the finite axially dispersed reactor which are either semi-infinite sections of finite dispersion or well-mixed sections of tinite capacity. The findings possess features akin to those found in Part II[q for case 1 but obviousl...

A transparent dual-channel microreactor with highly enhanced contact area-to-volume ratio was fabricated for efficient photosensitized oxygenations. The dual-channel microreactor shielded with polyvinylsilazane (PVSZ) consisting of an upper channel for liquid flow and a lower channel for O(2) flow, allows sufficient phase contact along the parallel channels through a gas permeable PDMS membrane...

Computational fluid dynamics (CFD) is a popular tool in the water industry for assessing ultraviolet (UV) reactor performance. However, due to the size of open-channel-type UV reactor systems, the CFD model requires significant computational time. Thus, most evaluations have been conducted using very simplified models. In order to ensure the reliability of this simplified CFD model, precise num...

An automated multi-channel continuous-flow analyzing system was constructed for the rapid measurement of both the tota} amino acid content and the L-gtutamate content of green tea infusions. i.-Glutamate in samples was oxidized and deaminated enzymaticatly in a channel -'ith a mini-reactor that "'as packed with i.-glutamate oxidase immebilized on glass beads, and the evolyed ammonium ions were ...

A micro-channel heat sink is a promising cooling method for high power integrated circuits (IC). However, the understanding of such a micro-channel device is not sufficient, because the tools for studying it are very limited. The details inside the micro-channels are not readily available. In this letter, a micro-channel heat sink is comprehensively studied using the integrated temperature sens...

The paper demonstrates the development of a numerical algorithm to solve a set of nonlinear hyperbolic equations in time domain in Eulerian frame of reference using a characteristics based finite difference implicit scheme to analyze density wave oscillations in boiling water nuclear reactor. The present algorithm removes the uncertainties existing in literature over the treatment of boundary c...

Objective: In this article, a numerical study is conducted on mixing of two fluids in the liquid phase with two different concentrations of a chemical species in the electro-osmotic flow. Methods: The base liquid is an electrolyte which flows in a two-dimensional micro-channel having electrically charged walls. Lorentz electric force, which is used as stimulating flow factor, is created by appl...

The stainless steel bipolar plate has received much attention due to the cost of graphite bipolar plates. Since the micro-channel of bipolar plates plays the role of fuel flow field, electric connector and fuel sealing, an investigation of the deep drawing process for stainless steel micro-channel arrays is reported in this work. The updated Lagrangian formulation, degenerated shell finite elem...
