A COMSOL Multiphysics®-based Model for Simulation of Methane-Hydrate Dissociation by Injection of Superheated Carbon Dioxide

M. Gharasoo[1], C. Deusner[1], N. Bigalke[1], M. Haeckel[1]
[1]Department of Marine Geosystems, GEOMAR - Helmholtz Centre for Ocean Research, Kiel, Germany

Immense amounts of methane are stored as gas-hydrate deposits in deep layers of marine sediments. This has raised considerable interest to develop strategies for producing natural gas from marine hydrates. One potential production strategy is the injection of supercritical CO2 into ... Mehr lesen

Analyte Capture from Liquid Samples: Size Matters

M. Weber[1], M. Reed[1]
[1]Yale University, New Haven, CT, USA

Arrays of vertical pillars, Micro Purification Chips, have been widely used for analyte capture from liquid samples [Henderson et. al, 2006], [Toner et. al, 2007], [Stern et. al, 2010]. However exact understanding of the capture efficiency mechanisms has not been previously explained. ... Mehr lesen

The Effect of Electrolyte Flow Slots in Tooling Electrodes on Workpiece Surface Finish in Electrochemical Machining

B. Bingham[1]
[1]Oregon State University, Corvallis, OR, USA

Electrochemical machining (ECM) uses electrolysis to precisely remove material at high rates. ECM has many advantages over conventional machining: no tool wear, no induced mechanical or thermal stresses, high removal rates virtually independent of material hardness or strength, and ... Mehr lesen

Evaluation of Performance of Enzymatic Biofuel Cells with Microelectrode Arrays Inside a Blood Artery via Finite Element Approach

C. Wang[1], Y. Song[1]
[1]Florida International University, Miami, FL, USA

Enzymatic biofuel cells (EBFCs) are considered as a promising candidate for powering miniature implantable devices. In order to predict the performance in the human blood artery, we simulated a 3D EBFC chip with highly dense micro-electrode arrays. In this simulation using COMSOL ... Mehr lesen

Simulation of the Plasma Generated in a Gas Bubble

L. Z. Tong[1]
[1]Keisoku Engineering System Co., Ltd., Tokyo, Japan

The plasmas generated in water involve various physical phenomena such as flows agitated by bubbles, high electric fields for breakdown, discharges in bubbles with size variation, and so on. In this paper, studies have been made on the simulation of plasmas generated in bubbles with size ... Mehr lesen

Modeling Bioelectrochemical Systems for Waste Water Treatment and Bioenergy Recovery with COMSOL Multiphysics®

T. Oyetunde[1], D. Ofiteru[1], J. Rodriguez[1]
[1]Masdar Institute of Science and Technology, Abu Dhabi, United Arab Emirates

Most conventional wastewater treatment processes are quite energy-intensive. Global wastewater production is increasing due to growth in population, industrialization, and urbanization, creating an urgent need for energy-efficient wastewater treatment technologies. Moreover, waste ... Mehr lesen

Numerical Simulation of Forced and Static Smoldering Combustion

S. Singer[1], W. H. Green[1]
[1]Massachusetts Institute of Technology, Cambridge, MA, USA

Transient, two-dimensional (axisymmetric) simulations of a cigarette subject to realistic static and forward smoldering cycles were performed. The computational domain consists of a porous packed bed of tobacco and a filter surrounded by a thin, porous paper and a region of surrounding ... Mehr lesen

Singlet Oxygen Modeling for PDT Incorporating Local Vascular Oxygen Diffusion

T. C. Zhu[1], B. Liu[1]
[1]University of Pennsylvania, Philadelphia, PA, USA

Singlet oxygen (1O2) is the major cytotoxic agent that kills cells during photodynamic therapy (PDT). Based on a previously-developed model, the distance-dependent reacted 1O2 can be numerically calculated using finite-element method. We improved the model to include microscopic kinetic ...

Computational Fluid Dynamics for Microreactors Used in Catalytic Oxidation of Propane

S. Odiba[1], M. Olea[1], S. Hodgson[1], A. Adgar[1]
[1]Teesside University, School of Science and Engineering, Middlesbrough, United Kingdom

This research deals with the design of suitable microreactors for the catalytic oxidation of volatile organic compound (VOCs), using propane as a model molecule. The microreactor considered consists of eleven parallel channels, in which an Au/Cr/γ-Al2O3-catalyzed combustion reaction ... Mehr lesen

Advancements in Carbon Dioxide and Water Vapor Separations Using COMSOL Multiphysics®

J. Knox[1], R. Coker[1], R. Cummings[1], C. Gomez[1], G. Schunk[1]
[1]NASA, Marshall Space Flight Center, Huntsville, AL, USA

Some NASA efforts are focused on improving current systems that utilize fixed beds of sorbent pellets by evaluating structured sorbents, seeking more robust pelletized sorbents, and examining alternate bed configurations to improve system efficiency and reliability. For the bulk ... Mehr lesen
