In this paper, a metallic honeycomb structure is used as a heat exchanger in order to improve the hydrogen refuelling time for an alanate storage system. Using COMSOL software, the heat exchanger structure and the hydride bed are modeled as a two separate media and the governing equations describing the physics phenomena occurring during the loading process, are solved. The simulation results ...

In this paper, COMSOL Multiphysics software is utilized as a finite element forward solver to obtain the electromagnetic fields at the receiving antennas while the breast is illuminated by one antenna in the array. Geometry consists of coronal slices of the 3-D breast. Simulations are done by a MATLAB code which runs COMSOL finite element solver and collects the data at the receiving antennas at ...
Fibre-Optic Microsensor Based on Surface Plasmon Resonance in a Microfluidic Cell : An Experimental and Numerical Multiphysics Approach

In the last decade, the surface plasmon resonance (SPR) has become a very sensitive technique for real-time detection in many application areas. Considering the fiber optic concept and the important needs for analyzing biomolecular reactions through automated and miniaturized components, fiber optic sensors based on the SPR technique are becoming an important choice in the field of sensing. In ...

To understand origins and consequences of drying phenomenon during composting, a compositional drying model of a partially water-saturated porous media coupled with biodegradation has been developed. The different simulations carried out under COMSOL Multiphysics demonstrate the ability of the model to well describe the compositional drying of a partial water-saturated porous media and point out ...

This study aims to numerically investigate on a passive solar system for indoor heating called as \"Trombe wall\". The transient buoyancy driven flow characterizing that system and the thermal distribution are solved by numerically integrating the governing equations in COMSOL Multiphysics environment. Simulations are carried-out for a time range corresponding to 12 days. The results are ...

Controlling electric field distribution in high voltage components is critical to avoid excessive electric stress on the insulation and thus reducing the risk of insulation breakdown and damage to equipment. For subsea applications this is even more important due to the costs involved in accessing and replacing the damaged parts. This paper describes how COMSOL Multiphysics has been used for ...
Impact of Velocity and Interfacial Tension on the Performance of Horizontal Wells in Gas Condensate Reservoirs

Drilling horizontal wells (HWs) has recently received renewed attentions with the increasing trend in exploitation of tight gas reservoirs. An accurate estimation of productivity of such systems using a numerical simulator is a challenging task, because its 3D simulation requires a fine grid exercise to capture the abrupt variation of fluid and flow parameters around the wellbore. This is ...

A fuel cell is an electrochemical system, which converts chemical energy into electricity by a controlled reaction of hydrogen and oxygen. The performance of the electrode is likewise determined by its material and the microstructure. The simulations were performed directly on reconstructions of real electrodes, obtained from focused ion beam (FIB) tomography. A finite element method (FEM) ...

We investigate and compare the characteristics of the fundamental guided mode sustained by a subwavelength plasmonic slot waveguide for three types of metals: gold, silver and aluminium. This is done in terms of mode effective index, propagation length, confinement and, as the mode under study is quasi-TEM, we also develop a transmission line model that can be useful in the design of optical ...
