Poromechanics Investigation at Pore-scale Using Digital Rock Physics Laboratory

S. Zhang[1],
N. Saxena[2],
P. Barthelemy[1], and
M. Marsh[1]
[1]Visualization Sciences Group, Burlington, MA, USA
[2]Stanford University, Palo Alto, CA, USA

Understanding the rock structure at nano to micro scale is of growing importance in geology, oil and gas, and hydrology. New approaches that relies on a variety of high resolution 3D imaging techniques offered tremendous potential. These new approaches, in the meanwhile, introduce ... Per saperne di più

Solution of Inverse Thermal Problem for Assessment of Thermal Parameters of Engineered H2 Storage Materials

I. Fedchenia, and B. van Hassel
United Technologies Research Center
East Hartford, CT

Materials based H2 storage systems for light duty vehicles need to meet challenging performance targets that have been developed by the FreedomCAR and Fuel Partnership. On-board reversible metal hydrides are typically integrated with heat transfer surfaces, e.g. in fin and tube heat ... Per saperne di più

Modeling a Cooling Skylight

M. Fält, and R. Zevenhoven
Thermal and Flow Engineering Laboratory, Department of Chemical Engineering
Åbo Akademi University
Turku
Finland

Air-conditioning produced by traditional vapor compression cycle is an energy demanding operation. By using passive cooling methods is it possible to avoid, or at least reduce, the need for vapor compression cooling. A passive radiative cooling method could be a three windowed skylight, ...

Densification and Shape Change of Calcined High Level Waste During Hot-Isostatic Pressing

T. Burnett, and D. Lower
CH2M-WG Idaho, LLC
The Idaho Cleanup Project at the Idaho National Laboratory
Idaho Falls, ID

Hot Isostatic Pressing (HIP) has been selected as a means of treating calcined high level waste (HLW). The process combines high temperature and pressure to densify the HLW in to a mineral similar to the geologic formulation of granite. This study uses COMSOL to predict densification ...

Computational Acoustic Attenuation Performance of Helicoidal Resonators

W. Lapka
Poznan University of Technology
Poznan, Poland

This paper concerns the problem of obtaining proper acoustic attenuation performance through computations. COMSOL was used to solve acoustics systems with helicoidal resonators in the frequency domain. Based on the studies of insertion and transmission loss of helicoidal resonators, a ...

Surface Aeration System Modeling using COMSOL

G. Selembo, P. Selembo, J. Stanton, and G. Paulsen
University of North Carolina
Charlotte, NC

Surface aeration systems are used in the wastewater treatment industry for the transfer of oxygen in the activated sludge process. These systems are capital intensive and also require a significant amount of energy to operate. Scale-up and design of these systems is largely empirical, ... Per saperne di più

Finite Element Analysis of Integrated Circuit Interconnect Lines on Lossy Silicon Substrate

S. Musa[1], M. Sadiku[1], and A. Emam[2]

[1]Roy G. Perry College of Engineering, Prairie View A&M University, Prairie View, TX
[2]Information Systems Department, King Saud University, Riyadh, Saudi Arabia

The silicon substrate has a significant effect on the inductance parameter of a lossy interconnect line on an integrated circuit. It is essential to take this into account in determining the transmission line electrical parameters. In this paper, a new quasi-TEM capacitance and ... Per saperne di più

Accurate Parameters Extraction of Multiconductor Transmission Lines in Multilayer Dielectric Media

S. Musa[1], M. Sadiku[1], and O. Momoh[2]
[1]Roy G. Perry College of Engineering, Prairie View A&M University, Prairie View, TX
[2]Indiana University-Purdue University

Development of very high speed integrated circuits is currently of great interest for today\'s technologies. This paper presents the quasi-TEM approach for the accurate parameters extraction of multiconductor transmission lines interconnect in single, two, and three-layered dielectric ...

Solving the Paraxial Wave Equation using COMSOL

P. Mikulski, K. Mcilhany, and R. Malek-Madani
United States Naval Academy
Annapolis, MD

Here we present and discuss numerical solutions to the paraxial wave equation using COMSOL (2D, PDE, General Form, time-dependent analysis). Ultimately, the goal is to extend this treatment of free-space beam propagation to the case of propagation through a medium that is non-uniform ... Per saperne di più

Designing Magnetic Coils from the Inside Out

C. Crawford, and D. Wagner
University of Kentucky
Lexington, KY

Traditionally the design cycle for magnetic fields involves guessing at a reasonable conductor and magnetic material configuration, using finite element analysis (FEA) software to calculate the resulting field, modifying the configuration, and iterating to produce the desired results. We ... Per saperne di più
