In metallurgy, the use of numerical models is popular because of the many coupled physical phenomena that occur during the various processes. For instance, the resulting shape and metallurgical state of a material are very sensitive to changes in temperature. The drop in temperature of ... En savoir plus

Smouldering is flameless combustion which depends on an exothermic surface reaction occurring within a porous medium. It is harnessed by engineers to destroy organic liquid wastes in soil as the technology Self-sustaining Treatment for Active Remediation (STAR). During this remediation ... En savoir plus

This research presents the design, simulation, and characterization of novel resonator structures based on the principles of coupling electric fields using periodic metamaterial-inspired configurations using COMSOL Multiphysics RF module. The resonators are meticulously crafted to ... En savoir plus

Microalgae biomass is an essential part of the global ecosystem. Not only is it responsible for 50% of the global oxygen but also proved to be useful in the development of organic polymers, antioxidants, pharmaceuticals, and feedstocks for aquatic animals. It is considered as an ... En savoir plus

We present a numerical model for simulating highly nonlinear electrokinetic phenomena, which occurs at high zeta potentials. In this model, the electric double layer is realized by solving a partial differential equation (PDE) on the double-layer-inducing surface. We also allow for a ... En savoir plus

In this study fluid-dynamical and thermal performance of active chilled beams is investigated by 2D and 3D modelling in COMSOL Multiphysics. Three different typologies of those air conditioning systems are considered. Results, obtained for typical range of variation of operational ... En savoir plus

Acoustic landmine detection is accomplished using a loud speaker as an airborne source to generate low-frequency waves that enter the soil at a certain incident angle. At a specific frequency, the landmine will "vibrate" at resonance, imparting a certain velocity on the soil particles ... En savoir plus

High power consumption chips have already become a major challenge for modern processors causing low thermal performances. Existing thermal solutions are not able to solve these high temperature issues efficiently. Two-phase cooling devices such as heat pipes and vapor chambers have ... En savoir plus

In recent years, with the rise of quantum optical technologies, there has been a spurring research interest growing on single-photon emitters (SPE). To date, the focus in engineering improved SPE has been mainly towards better enhancement overlooking the tenuous manufacturing process ... En savoir plus

The right way to design dedicated controller for a particular device or process is to compute an adequate and representative model. In the case of Magnetic Levitation Systems, the mathematical modelling via ordinary differential equations is limited by the analytical functions ... En savoir plus
