Modeling of Transport Phenomena in Gas Tungsten Arc Welding of Ni to 304 Stainless Steel

A. Bahrami[1], D. K. Aidun[1]
[1]MAE Department, Clarkson University, Potsdam, NY, USA

COMSOL Multiphysics® is used to simulate the transport phenomena in arc welding of Nickel to 304SS. Electric Currents (ec) and Magnetic Fields (mf) are used to solve for the Lorentz force which is one of the volume forces. Laminar Flow (spf) is used to simulate flow field. The Lorentz ... 詳細を見る

Development of a Multiphase, Multispecies Droplet Evaporation Model for Optimization of Desiccation Preservation Techniques

A. Sinkevich[1], S. Bhowmick [1], M. Raessi[1]
[1]University of Massachusetts Dartmouth, North Dartmouth, MA, USA

Biopreservation deals with the protection and storage of complex biologics such as proteins, lipids, and recently, mammalian cells. One preservation method, known as lyopreservation, involves placing a biologic inside a water droplet with some type of sugar excipient (sucrose, trehalose, ... 詳細を見る

Computational Modeling of the Electrohydrodynamics Influencing Trace Mercury Adsorption within Electric Utility Electrostatic Precipitators

H. Clack[1]
[1]University of Michigan, Ann Arbor, MI, USA

Anthropogenic mercury (Hg) emissions increase the risk of neurological and neonatal health effects in humans through fish consumption. There are several technological approaches to controlling mercury emissions from coal combustion, including the injection of a powdered mercury sorbent ... 詳細を見る

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 ... 詳細を見る

Numerical Modeling of the Bistability of Electrolyte Transport in Conical Nanopores

H. White[1], L. Luo[1]
[1]Department of Chemistry, University of Utah, Salt Lake City, UT, USA

A characteristic feature of nanochannels is that surface properties (e.g., electrical charge) play a more significant role in the transport of fluid and electrolyte. Two oppositely directed flows (electroosmotic flow and pressure-driven flow) determine the flow profile at the nanopore ... 詳細を見る

Numerical Study of the Controlled Droplet Breakup by Static Electric Fields inside a Microfluidic Flow-focusing Device

Y. Li[1], K. Nandakumar[1], M. Jain[1]
[1]Louisiana State Univeristy, Baton Rouge, LA, USA

Conventional passive microfluidic flow-focusing devices confront difficulties in controlling droplet sizes in dripping regime especially when the dispersed phase has a large viscosity. It is reported that external electric field can be used to manipulate the droplet breakup. In the ... 詳細を見る

Simulation of Transdermal Toxin Expulsion via Adsorptive Dermal Patch using COMSOL Multiphysics®

H. Kwon[1], M. Hess II[1], R. M. Polski
[1]Andrews University, Berrien Springs, MI, USA

Mathematical skin models play an important role in fields such as transdermal drug delivery and assessment of dermal exposure to industrial chemicals. Extensive research has been conducted on modeling skin for transdermal drug delivery; however, little effort has been made to view the ... 詳細を見る

Claus Process Reactor Simulation

J. Plawsky[1],
[1]Rensselaer Polytechnic Institute, Troy, NY, USA

A model was developed to simulate the reaction, concentration field, flow field, and temperature distribution inside a Claus reactor for converting hydrogen sulfide to sulfur. The model considered two ideal reactors, a continuous stirred tank reactor and a plug flow reactor. As expected, ... 詳細を見る

Simulation of Geomechanical Reservoir Behavior during SAGD Process Using COMSOL Multiphysics®

X. Gong[1], R. Wan[1]
[1]University of Calgary, Calgary, AB, Canada

THM (Thermo-Hydro-Mechanical) behavior of the reservoir during SAGD (Steam-Assistant-Gravity-Drainage) was studied through a proper constitutive modeling of the porous media. Specifically, a generalized density-stress-fabric dependent elasto-plastic model with stress-dilatancy and ... 詳細を見る

Modeling Revitalization of Atmospheric Water

R. Coker[1], J. Knox[1]
[1]NASA, Marshall Space Flight Center, Huntsville, AL, USA

Developments intended to improve system efficiency and reliability for water and carbon dioxide separation systems to be used on crewed vehicles combine sub-scale systems testing and multiphysics simulations. This paper describes the development of COMSOL Multiphysics® simulations in ... 詳細を見る
