FMR spectra of the periodic microstructures (one-dimensional magnonic crystals, 1D MCs) were obtained using COMSOL with use partial differential equation interface. Results of these calculations were successfully compared with an experimental data for Damon-Eshbach (DE) and Backward-Volume (BV) geometries. The presented tool allows to analyze periodic structures with various geometries and ...

Pressure sensors operating at the temperature higher that 500 °C are absent in the world market. Our goal is to develop a pressure sensor that can operate at the high temperature up to 700 °C. Our sensor will be made up of a ceramic sensible element and a metallic case. The sensible element will be a ceramic beam with a Weathstone bridge on its surface. A structural analysis on the case has been ...

The paper presents recent results concerning the experimental mechanical characterization, the numerical modeling and the design of micro-needles used in the construction of probe heads for wafer testing. A fully coupled electro-thermal model was created using COMSOL and combined to a research-oriented thermo-mechanical Finite Element (FE) code in order to accurately reproduce the micro-needle ...

The Swedish Organization for Radioactive Waste (SKB) is considering disposal High Level Wastes in a deep underground repository. Bentonite clay is planned to be used in the near-field of the waste packages as buffer material. The buffer is expected to provide a favorable environment with limited radionuclide migration due to slow diffusion and retardation by sorption and cation-exchange effects. ...

This paper presents a numerical study of the deposition of submicron charged spherical particles caused by convection, Brownian and turbulent diffusion in a pipe with a smooth wall and with a cartilaginous ring wall structure (see figure). The model is supposed to describe deposition of charged particles in generation 0 (trachea) of the human lung.The problem is defined by solving the fluid flow ...

Ground Heat Exchangers (GHXs) are rarely installed horizontally in linked ground source heat pumps used for space conditioning, because their energetic performance is lower than in the vertical solution. However, the horizontal one holds several advantages: it is easy to carry out and upkeep, it is more compliant with environmental regulations, and interferes marginally with groundwater systems. ...

We present numerical models and field data that aid understanding of volcano-tectonic processes related to the propagation of inclined sheets and dykes under a stress field resulting from the inflation of a shallow magma chamber. Structural field data from the classical Cuillins cone-sheet complex (Isle of Skye) show that sheets have a constant average dip angle (45°), with pure dilational or ...

Groundwater is a key factor affecting mine operations worldwide. On one hand, both underground and open pit mines need to pump out groundwater in order to proceed with mineral extraction and increase the stability of rock slopes. On the other hand, groundwater abstractions can produce undesired environmental and social impacts, which should be anticipated in the environmental impact assessments ...
