Reflow soldering is a widely used technique in electronics manufacturing that facilitates the precise and automated assembly of electronic components onto printed circuit boards (PCBs). This method is indispensable for the efficient production of intricate electronic devices, ensuring ... En savoir plus

Macroscopic modeling of fluid flow and thermal diffusion, in a porous medium, requires the description of equivalent properties (permeability, conductivity and diffusivity). However, depending on the microstructure topology of the porous medium and the fluid flow regime at the ... 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

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

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

Liquid atomization relies on a variety of forces that disturb the surface of the liquid. In the case of flow-blurring (FB) atomization, turbulent structures are induced within the liquid channel to achieve this effect. It is known that the transition from the conventional flow-focusing ... En savoir plus

Soil sedimentation and consolidation, whether they are naturally or anthropically driven processes, are closely interconnected. While theoretical models are available to separately describe the behaviour of either ‘fluid’ suspensions or ‘solid’ soil, no well-established unified theory ... 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

Finite Element Method (FEM) simulations are vital in the design of loudspeakers, providing an efficient alternative to traditional trial-and-error methods. This study aims to advance the understanding and optimization of loudspeaker design focusing particularly on the influence of ... En savoir plus
