In the present work, numerical simulations of a Monolith Reactor (MR) are carried out in order to develop a pre-design tool for industrial-scale reactors applied to highly exothermal reactions. The reacting circular channels (2-4 mm internal diameter) are coated with a few micron thick ... 詳細を見る
On the surface of an optical waveguide, there is an evanescent field. The evanescent field decays fast and this steep gradient can be used to pull nano- and microparticles down towards the waveguide surface. Radiation forces will propel the particle forward along the waveguide. Trapping ... 詳細を見る
Introduction: After more than 20 years of experience in EV applications, the sodium nickel chloride technology is fully mature for large scale energy storage. Early on, mathematical modeling of Na-MCl2 cell (M standing for Fe or Ni) has attracted attention to help identifying predominant ... 詳細を見る
During Physical Vapor Transport (PVT) growth of single 4H-SiC crystal and subsequent cooling down, thermal stresses lead to the multiplication of dislocations that are non-desirable for the semiconductor applications of this material. These dislocations induced by thermal stresses could ... 詳細を見る
The multilayer composite single mass cantilever is a MEMS energy harvester structure. The vibrating structure is under vacuum in hermetic MEMS. However, out-gassing during process integration and fabrication would cause air molecules (e.g. hydrogen, nitrogen, argon, water vapor, oxygen, ... 詳細を見る
INTRODUCTION: Nuclear magnetic resonance (NMR) spectroscopy is a broadly used research technique that exploits the magnetic properties of atomic nuclei with non-zero spin in order to determine the physical/chemical properties of the molecules in which they are contained. However, NMR has ... 詳細を見る
Combination of additive manufacturing (AM) and topological optimization with COMSOL Multiphysics® software offer new opportunities in mechanical design without limitation on structure geometry. Fused Deposition Modeling is a widely used AM process which is affordable with a free control ... 詳細を見る
Among the new features introduced by the latest versions of COMSOL Multiphysics® software, the opportunity of building up customized model interfaces by exploiting the Application Builder is for sure one of the most promising. Arising from this concept, the Certified Consultant BE CAE ... 詳細を見る
Heat transfer inside a refrigerated truck is a key phenomenon that governs the temperature inside the truck and the regulation of the cooling system. Up to now, a lot of experimental studies ([Tso et al., 02]) have been carried out to assess the effect of opening the door and to minimize ... 詳細を見る
Introduction: The use of microwave energy for thermal cracking (from thermal stress and water pore pressure) of lignite-coal briquettes increases the lignite friability [1] and is beneficial for later chemical treatment inside a gasifier (for methanol production for example). An ... 詳細を見る
