Laminar Fluid Flow and Heat Transfer Studies of an Electrical Conducting Fluid Subject to Combined Electric and Magnetic Fields

E. Gutierrez-Miravete[1], T. DePuy[2], and X. Xie[2]
[1]Rensselaer at Hartford, Hartford, CT
[2]Pratt & Whitney, East Hartford, CT

The flow of electrically conducting fluids such as liquid metals is significantly affected by applied electric and magnetic fields. The effect has important industrial applications in metallurgy, nuclear technology and other fields. This paper described results of a series of studies ... En savoir plus

Time Domain Analysis of Eddy Currents in Saturating Magnetic Materials

S. Thompson
Applied Research Laboratory
Penn State University
State College, PA

Eddy current phenomena in conducting magnetic media are well understood, although the detailed behavior at high drive levels leading to magnetic saturation are not always well explained. This paper considers the example of an infinite cylindrical magnetic core with an external coil. At ... En savoir plus

Complex Geometry Creation and Turbulent Conjugate Heat Transfer Modeling

I. Bodey[1], R. Arimilli[1], and J. Freels[2]
[1]Dept. of Mechanical, Aerospace and Biomedical Eng., The University of Tennessee, Knoxville, TN
[2]Research Reactors Division, Oak Ridge National Laboratory, Oak Ridge, TN

The High Flux Isotope Reactor (HFIR) at the Oak Ridge National Laboratory (ORNL) is an 85 MW, light-water moderated, research reactor that operates at low temperature and high pressure. The HFIR is presently scheduled to convert from a high enriched uranium fuel (HEU) to a low enriched ... En savoir plus

Modeling System Dynamics in a MEMS-Based Stirling Cooler

D. Guo, A. McGaughey, G. Fedder, M. Lee, and S. Yao
Carnegie Mellon University
Pittsburgh, PA

Micro-scale devices based on the Stirling cycle are an attractive choice for chip- and board-level electronics. A new Stirling cycle micro-refrigeration system composed of arrays of silicon MEMS cooling elements has been designed. COMSOL is used to evaluate the thermal performance of ... En savoir plus

Reconstruction for Interstitial Diffuse Optical Tomography (iDOT) for Human Prostate

X. Liang, K. Kang-Hsin Wang, and T. Zhu
University of Pennsylvania
Philadelphia, PA

Determination of tissue optical properties distributions is very important for determining light fluence distribution during photodynamic therapy (PDT). In this study, an interstitial diffuse optical tomography (iDOT) system was used to characterize the spatial distribution of optical ... En savoir plus

Deformation of Biconcave Red Blood Cell in the Dual-Beam Optical Tweezers

Y. Sheng, and L. Yu
University Laval
Quebec City, QC
Canada

A biconcave-shaped Red Blood Cell was trapped and deformed in a dual-trap optical tweezers. The two highly focused trapping beams of Gaussian intensity distribution were modeled as background field in the COMSOL Radio Frequency Module. The 3D radiation stress distribution on the cell ...

Modeling of the Heat Transfer Between a CO2 Sequestration Well and the ...

Modeling of the Heat Transfer Between a CO₂ Sequestration Well and the Surrounding Geological Formation

B. Sponagle[1], M. Amadu[2], D. Groulx[1], and M. Pegg[2]
[1]Mechanical Engineering, Dalhousie University, Halifax, NS, Canada
[2]Process Engineering and Applied Science, Dalhousie University, Halifax, NS, Canada

In a carbon sequestration system CO2 would be pumped down a well and into a reservoir at supercritical temperatures and pressures. An important consideration is the long term stability of the reservoir. The goal of these simulations is to thermally model the injection well and ... En savoir plus

Thermal Properties of Copper Tungsten with Copper Via Composite

J. Ma[1], A. Parker[1], and K. Kuan[2]
[1]Southeastern Louisiana University, Hammond, LA, USA
[2]Torrey Hill Technology LLC, SanDiego, CA, USA

This study focuses on a low-cost composite material based on CuW with Cu via, which functions as a more efficient thermal path for heat conduction. A 50mm X 50mm X 1mm CuW(15/85) speciman consists an array of 30X30 uniformly distributed cylindrical Cu via attaching to a microprocessor ... En savoir plus

Wall Effect on A Spherical Particle Settling along The Axis of Cylindrical Tubes Filled with Carreau Model Fluids

D. Song[1], R. Gupta[1], and R. Chhabra[2]
[1]Dept. of Chemical Engineering, West Virginia University, Morgantown, WV
[2]Indian Institute of Technology, Kanpur, India

The effect of finite boundaries on the drag experienced by a rigid sphere settling along the axis of cylindrical tubes filled with Carreau model fluids has been examined systematically over a wide range of condition. As expected, the presence of finite boundaries leads to an increase in ... En savoir plus
