In this paper, a numerical study is conducted on the melting and solidification process of metal foam/paraffin wax with cyclic heating and cooling. A mathematical model based on the Brinkman-Frochheimer extended Darcy equation and the local thermal non-equilibrium model (LTNE) is ... En savoir plus
The aim of this study is to compare the diffraction efficiency of a sinusoidal diffraction grating numerically calculated using COMSOL Multiphysics® with the measured results performed with a custom-made equipment and calculations using Bessel functions. A diffraction grating with the ... En savoir plus
A power supply is generally used in many electrical devices. In order to deliver uniform power irrespective of time variation, most plasma equipment also uses a power source. Therefore, the power condition in plasma simulations is essential. In time-dependent models using a current ... En savoir plus
Electroporation is the process of creating temporary hydrophilic pores in the cell membrane by applying an external electric field of specific strength and duration. It is used for gene transfection, and transport of other useful biomolecules and therapeutic drugs into the cell. When a ... En savoir plus
The most common method for in-situ recovery of oil sands is Steam Assisted Gravity Drainage (SAGD). SAGD is based on injecting pressurized steam into the ground to heat up the highly viscous bitumen and reduce its viscosity allowing oil to flow. This process is energy and emissions ...

In this research work, we developed a virtual model to examine the electrical conductivity of multilayered thin films when positioned above a single layer and multilayers of graphene, and flexible polyethylene terephthalate (PET) substrate. Additional structured thin films were ... En savoir plus
Emerging battery technologies are addressing applications of renewable and fossil fuel energy sources since they can store and release energy on demand. In recent years significant strides have been made in lithium battery technology. Lithium batteries are the primary sources of power in ... En savoir plus
With the evolving trend of electrification in transportation, electric machines with higher power density and higher efficiency are demanded which results in the thermal limit of the stator winding becoming more of a key constraint. The achievable current density in stator windings is ... En savoir plus
Modern home audio products are starting to feature dedicated upward firing height channel speakers, which are a combination of unique physical speaker design and special signal processing, to reproduce audio as if the sound source is located in the ceiling. Due to slim form factor design ... En savoir plus
This paper presents the design and simulation results of a MEMS-actuated deformable mirror (DM) consisting of a 20 × 20 Lorentz-force actuator array bonded to a flexible mirror. The DM is the critical component of an Adaptive Optics (AO) system targeted for ground-based telescope ... En savoir plus
