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 ... Read More
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 ... Read More
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 ... Read More
Microwave impedance microscopy (MIM) is a novel mode of atomic force microscopy that can measure topography and local electrical impedance simultaneously and with nanometer spatial resolution [1]. This technique is typically used qualitatively, identifying defects in nanodevices or ... Read More
The Purpose of this paper is to develop a thermal model using COMSOL Multiphysics® software that aims to get an idea of the heat flow around the ASIC, as well as to address the thermal issues for integrated circuits at the tongue board. However, we need sources of heat simulations to map ... Read More
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 ... Read More
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 ... Read More
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 ... Read More
We describe simulations performed in COMSOL Multiphysics® of the precipitation of helium (He) on solid-state interfaces. The non-uniform precipitation of He at certain interfaces is a result of a heterogeneous energy distribution in the interface plane: He wets high interface energy ( ... Read More
