Poromechanics Investigation at Pore-scale Using Digital Rock Physics Laboratory
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 ... En savoir plus
Solution of Inverse Thermal Problem for Assessment of Thermal Parameters of Engineered H2 Storage Materials
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 ... En savoir plus
Modeling a Cooling Skylight
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
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
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 ... En savoir plus
Surface Aeration System Modeling using COMSOL
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, ... En savoir plus
Finite Element Analysis of Integrated Circuit Interconnect Lines on Lossy Silicon Substrate
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 ... En savoir plus
Accurate Parameters Extraction of Multiconductor Transmission Lines in Multilayer Dielectric Media
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 ... En savoir plus
Solving the Paraxial Wave Equation using COMSOL
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 ... En savoir plus
Designing Magnetic Coils from the Inside Out
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 ... En savoir plus
