The core unit of desiccant cooling systems is a dehumidifying device, in most cases a wheel made of inert material coated with an adsorbent (silica gel in the present work). Two sections can be identified: air to be dehumidified was passed through the process section, while in the ... En savoir plus
Knowledge of the effect of fractures on fluid flow and transport is of great interest in many fields. In radioactive waste disposal the interest in fractures within concrete structure is because they are mostly more permeable than the matrix, there is less or no sorption and because long ...

Concentrated photovoltaic systems with high efficiency solar cells are being widely investigated, aiming at improving the cost-efficiency balance in the solar energy field. Different cell types are in use: e.g., high concentration triple junction cells, reaching efficiencies of the order ... En savoir plus
In this paper, the influence of carbon nanotube (CNT) in a metal matrix on the buckling behavior of the resulting nanocomposite plate is studied. The Young's moduli of CNT reinforced nanocomposite are predicted first using the representative volume element (RVE) method. CNTs are ... En savoir plus
Auxiliary Power Units can play an important role in reducing vehicle emissions, especially in diesel and kerosene driven vehicles. In conventional vehicles the electricity supply comes from a generator that is directly coupled to the propulsion engine. New generation of fuel cell APUs ... En savoir plus
Granular materials have been conventionally used for acoustic treatment due to their sound absorptive and sound insulating characteristics. An emerging field is the study of acoustical properties of multi-scale porous materials. An example of these is a double-porosity granular material ... En savoir plus
Ultrasound imaging probes are widely used for several types of diagnosis applications. In the present work we focus our attention on a disk-type probe, which is widely used in CW and PW operating conditions. In particular we present a 2D-axial symmetry FEM for the probe, capable to ...

The ITER-ECE transmission lines consist of smooth-wall circular waveguides, including miter bends and other components. The performance of the TL is crucial to ensuring that the requirements for the diagnostic to measure the plasma parameters are met. COMSOL Multiphysics® has a finite ... En savoir plus
A model for material damping is presented in terms of internal friction and in terms of a variation of stiffness. In the latter case the idea is that the stiffness increases if elastic energy is stored and decreases if elastic energy is released. In case of a single mass spring system ... En savoir plus
Anders B Nilsson graduated M. Sc. in engineering physics from Lund University in Sweden. He has been working in the R&D department at BD Medical as principal engineer and project leader since 2005. He uses COMSOL for a wide range of functions, such as early concept development and ... En savoir plus
