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 ... En Savoir Plus

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 ...

An MHD Study of the Behavior of an Electrolyte Solution Using 3D Numerical Simulation

L. P. Aoki[1], H. E. Schulz[1], M. G. Maunsell[1]
[1]University of São Paulo, São Carlos, SP, Brazil

This article considers a closed water circuit with square cross section filled with an electrolyte fluid. The conductor fluid was moved using an electromagnetic pump, in which a permanent magnet generates a magnetic field and electrodes generate the electric field in the flow. Thus, the ...

Simulating HFIR Core Thermal Hydraulics Using 3D-2D Model Coupling

A. Travis[1], K. Ekici[1], J. Freels[2]
[1]The University of Tennessee, Knoxville, TN, USA
[2]Oak Ridge National Laboratory, Oak Ridge, TN, USA

A model utilizing interdimensional variable coupling is presented for simulating the thermal hydraulic interactions of the High Flux Isotope Reactor (HFIR) core at Oak Ridge National Laboratory (ORNL). The model’s domain consists of a three-dimensional fuel plate and a two-dimensional ... En Savoir Plus

Fluid-Structure Interaction Modeling of High-Aspect Ratio Nuclear Fuel Plates Using COMSOL Multiphysics®

F. Curtis[1], K. Ekici[1], J. D. Freels[2]
[1]The University of Tennessee, Knoxville, TN, USA
[2]Oak Ridge National Laboratory, Oak Ridge, TN, USA

The High Flux Isotope Reactor at the Oak Ridge National Lab is in the research stage of converting its fuel from high-enriched uranium to low-enriched uranium. One of the areas being explored is the fluid-structure interaction phenomenon due to the interaction of thin fuel plates (50 ... En Savoir Plus

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 ... En Savoir Plus

Pros and Cons of Running COMSOL Multiphysics® Touch-Sensor Simulations on Amazon Web Services™

A. Gourevitch[1]
[1]Cypress Semiconductor Corp., San Jose, CA, USA

We report an implementation of parallel computing on Amazon Web Services™ (AWS) for touch-sensor modeling. COMSOL Multiphysics® was used to simulate an electromagnetic field distribution in a capacitive sensor assembly. Multiple COMSOL jobs were deployed on separate AWS instances and ... En Savoir Plus

Simulation, Fabrication and Observation of Plasmonic Halos

F. Ye[1], M. Burns[1], J. Merlo[1], M. Naughton[1]
[1]Department of Physics, Boston College, Chestnut Hill, MA, USA

We present the simulation, observation and systematic study of a novel optical phenomenon, a “plasmonic halo”, wherein optically pumped surface plasmons on circular silver microcavities form confined drumhead modes that, under off-resonant conditions, transform to colorful far field ...

Computer-aided Design of the Heating Section of a Continuous Kheer (Rice Pudding)-making Machine

S. Kadam[1], T. Gulati[2], A. Datta[1]
[1]Indian Institute of Technology, Kharagpur, India
[2]Cornell University, Ithaca, NY, USA

Kheer is a popular Indian dairy dessert prepared from concentrating milk with simultaneous cooking of rice grains. Conventional methods of preparing kheer have limited its mechanized production. Therefore, a conceptual design of continuous kheer-making machine has been prepared which ... En Savoir Plus

Modeling Flow and Deformation during Hot Air Puffing of Single Rice Kernels

T. Gulati[1], A. Datta[1]
[1]Cornell University, Ithaca, NY, USA

When rice is subjected to intense heating, it results in rapid evaporation of liquid water to vapor. As a consequence, large pressures are generated within the kernel in a span of 15s resulting in large volume changes causing the kernel to puff rapidly. Under suitable conditions, the ...
