It is common knowledge to readers of these COMSOL conference proceedings that COMSOL (as well as other established CFD codes) produces unstable numerical solutions of the Navier-Stokes equations without "consistent stabilization" and/or "inconsistent stabilization" (or similar ... En savoir plus
In this work we present a novel approach to enhance energy efficiency in cooling intake air for air conditioning (AC) systems in harsh environments using geothermal energy. We developed a 3D finite element model to simulate the heat transfer between underground soils/gravels and cooling ... En savoir plus
Porous guided bone regeneration (GBR) meshes are used in dentistry as a mechanical barrier to separate and protect the area of bone loss, providing space for new bone growth. An appropriate pore size can play a role, as important as its space-maintaining properties. The characteristics ... En savoir plus
In this paper, we present a study of the simulation of Directed Energy Deposition (DED) Additive Manufacturing (AM) using a multiphysics approach. We use a combination of Heat Transfer in Fluids, Solid Mechanics and Laminar Flow physics to accurately simulate the DED process. The ... En savoir plus
While common hot water storage geometries are slim and high, this work deals with the conversion of a preexisting cellar room into a hot water storage with an area of 550 m² and a height of only 2.9 m. Next to the poor area-to-height ratio, the room contains columns and bearers for ... En savoir plus
In view of an energy system based on fluctuating renewable sources, the use of thermal energy storage (TES) systems plays a crucial role. In particular, large-scale underground water-based TES represent a promising solution as demonstrated by a number of cases currently being established ... 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
Simulation of laser processes are more and more efficient. In some cases, as welding and additive manufacturing, the physical phenomena are complex, multi-physics and multi-phases, thus some assumptions have to be done. For Laser Powder Bed Fusion, a laser beam melts and vaporizes the ... En savoir plus
Abstract: In order to study thermal conditions and air flows in an office room, 3D FEM simulation model was created. The room is enclosed by walls, floor and ceiling which thermal characteristics are specified by typical heat transfer coefficients and specific heat capacities. Space ... En savoir plus
Solid-state batteries have emerged as a viable alternative to traditional liquid-based lithium-ion batteries, offering improved cost efficiency, safety, and environmental impact. Chlorine-rich lithium argyrodite (Li6PS5Cl) has emerged as a promising solid-state electrolyte, presenting ... En savoir plus
