Micro-tubular Solid Oxide Fuel Cells (mSOFC) are attracting more and more interest as new generation of energy conversion devices. Although commercial applications still suffer from high costs, there is a need for further improvement of the cell performance, durability and start-up. To resolve those challenges, knowledge of the distributions of species concentration, temperature and current ...

Electromagnetic sounding measurements utilize magnetic induction to constrain the interior geophysical properties of planetary bodies. Under some conditions, the Earth’s moon can be approximated by the response of a conducting sphere in a vacuum. Transient magnetic fields originating from the sun can interact directly with the moon, producing eddy currents that generate an induced magnetic ...

The objective of the study is to investigate the chiral separation of Tröger’s base enantiomers using batch chromatography. Because of its resolution, chromatography is often the preferred method for chiral separations. The separation of Tröger’s base is resolved by using the COMSOL Multiphysics® software. It is modeled by one dimension geometry, having the length of the column set and computed ...

In this work, we study the design of a new integrated system for Solar Water Heating that combines the solar thermal energy collection (primary circuit) with the heat storage (secondary circuit) into the same device. We have performed different finite element method simulations using COMSOL Multiphysics®, for solving the equations of heat transfer (conduction and convection) and those of fluid ...

In fractured reservoirs, much of the oil is stored in low permeable matrix blocks that are surrounded by a high permeability fracture network. Therefore, production from fractured reservoir depends on the transfer between fracture and matrix, which is critically dependent on their interaction. COMSOL Multiphysics® was implemented to model the process of penetration of the aqueous phase into an ...

The problem of storage, and release of thermal energy is an important challenge in various industrial fields. Several systems for thermal energy storage exist like phase change materials (PCM) and thermochemical storage . The first system usually addresses short term storage (day duration) while thermochemical storage are very interesting for longer duration (seasonal storage). However, ...

The Atlantis massif is a domal submarine seamount close to the mid-Atlantic Ridge at 30 °N. Close to the crest of the Massif, the Lost City hydrothermal field (LCHF) has been active for at least 120,000 years, venting fluids with a temperature of 40-90 °C. 5 km north of Lost City, a temperature profile has been measured in IODP Hole 1309D, with a near-conductive thermal gradient of ~100 °C/km ...

The Life+ GreenWoolF project is aimed at demonstrating that green hydrolysis with superheated water is an effective way to convert wool wastes into organic nitrogen fertilizers. The core of the process is represented by the reaction tank (Figure 1) in which the hydrolyses reaction takes place. The temperature of the material during the reaction is one of the most influencing parameter and has to ...

Previous research into acoustic omnidirectional absorber (AOA) has shown the feasibility of forming acoustic black hole to guide the incident wave into the central absorptive cavity. However, major restrictions to practical applications exist due to complexity of designing metamaterials and unchangeable working states. Here, we propose two cylindrical, two-dimensional AOA schemes based on ...
