Efficient Geothermal Cooling in Harsh Environments: A Combined Experimental and Modelling Approach

Mohammed Al-Azba1, Ahmed Abotaleb2
1Qatar Environment and Energy Research Institute, HBKU, Qatar Foundation, Doha, Qatar
2ICube Laboratory, Université de Strasbourg-CNRS, 67000 Strasbourg, France

In this work we present a novel approach to enhance energy efficiency in cooling intake air for air conditioning (AC) systems in harsh environments using geothermal energy. We developed a 3D finite element model to simulate the heat transfer between underground soils/gravels and cooling ... Read More

2SKB, Solna, Sweden

The study of bentonite erosion mechanisms in fractures is a problem of maximum interest to understand the long-term performance of the engineered barrier in deep geological repositories of spent nuclear fuel. In this context, erosion due to shear by seeping water, sedimentation due to ... Read More

Development of a Special COMSOL® Interface Based on an Alternative Model for Bentonite Re-Saturation

Michael Kröhn1, Lars Fromme2
1GRS gGmbH, Braunschweig, Germany
2Hochschule Bielefeld – University of Applied Sciences and Arts (HSBI), Faculty of Engineering and Mathematics, Bielefeld, Germany

Bentonite is a versatile material that is, among other things, envisaged in most countries worldwide for use in radioactive waste repositories to protect the waste canisters against groundwater. The thermo-hydro-mechanically (THM) coupled process of bentonite saturation is commonly based ... Read More

Modeling of Thermal Load and Electric Fields in Microfocus X-Ray Tubes

Dr. Vladimir Burlaka1, Thorsten Fröba1
1X-RAY WorX GmbH, Siemensstraße 26, 30827 Garbsen, Germany

The thermal load on the system components is one of the technical problems in the development of microfocus X-ray tubes. To improve their stability in long-term use, it is important to understand the physical phenomena and their influence on the system stability and filament lifetime. To ... Read More

Multiphysical Optimization of the Next Generation of Energy Efficient High Temperature Furnaces

1Faculty of Chemical Technology, University of Pardubice, Czech Republic

Micro-lenses with potential applications in optics on the surface of the various heavy-metal oxide glasses were created and studied experimentally [1-2]. Laser direct writing using continuous-wave laser emitting at 447 nm was successfully performed [2]. The aim of this study is to ... Read More

Common Mode Choke Electromagnetic Simulation

M. Balestrini1
1SCHURTER AG

Common mode chokes are used in electrical circuits to filter out the electromagnetic interference (EMI). The goal of this study is to simulate the impedance of the choke within a range of frequency from 0.01 MHz to 50 MHz. In this simulation model the COMSOL® AC/DC Module with magnetic ... Read More

High Speed Inductive eRPS Sensor Error Reduction Using COMSOL Multiphysics®
