The roof of a well known shopping place in Amsterdam collapsed during a storm with heavy rain showers in 2002. One of the main problems was the malfunction of the draining system. Another problem was that driving rain water apparently washed over edges that where designed to hold the ... Read More

Charged particle accelerators require large dipole fields with stringent homogeneity requirements needed to bend particle beams without defocussing. Commonly superconducting saddle coil magnets are used with an iron core to enhance the bore field. The iron uneven magnetization brings ... Read More

A new simple air-cooled inverter design is numerically investigated using COMSOL Multiphysics® software. The thermal-fluid analysis is based on a three-dimensional conjugate heat transfer model in which the flow field is assumed to be laminar. A rigorous mesh convergence was performed to ... Read More

ICP reactors are usually meter sized and driven at RF frequencies, for example at 13.56 MHz. We developed a miniature resonator allowing an inductive type of coupling of microwaves at 2.45 GHz to a plasma jet, flowing in ceramic tubes. Previous experiments and simulations show an ... Read More

In thin-film solar cells (a-Si:H, µc-Si:H, CIGS, etc.) scattering of light is very important to increase absorption of light in the active layers of solar cells. Today the most efficient thin-film solar cells are designed or deposited on random textured transparent conductive oxides ... Read More

This project utilizes the heat transfer module of the COMSOL Multiphysics environment to model the effects that an ohmic heating probe will have on neural tissue. The model quantifies the thermal impact of active components embedded on a neural micro probe by solving the Penne’s bioheat ... Read More

For the numeric investigations of the high temperature compact heat exchanger two numeric models with and without the regards of the velocity field development were used. The results of the comparison of the numeric and experimental data confirm the necessity of regarding the velocity ... Read More

A new experimental device has been developed in order to characterize the phase change material (PCM) thermal properties (thermal conductivity k, sensible and latent heat thermal energy storage, cp and Lf) in the solid phase, during the solid-liquid transition and in the liquid phase. It ... Read More

The hydro-mechanical (HM) numerical simulation of a shaft seal installed at a fracture zone in a hypothetical host rock using COMSOL is presented. Two different stages are considered in the numerical modelling. Stage 1 simulates the groundwater flow into an open shaft. Stage 2 simulates ... Read More

This paper is a part of a study on energy piles for heating and cooling of buildings. Energy piles are used for two reasons: (1) to transfer structural loads to foundation soils, and (2) to transfer heat from foundation soils to the building for space heating in winter time and for ... Read More
