Efficient Geothermal Cooling in Harsh Environments: A Combined Experimental and Modelling Approach
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 ... En savoir plus

Numerical Modeling of Bentonite Erosion due to Sedimentation in Sloping Fractures
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 ... En savoir plus
Development of a Special COMSOL® Interface Based on an Alternative Model for Bentonite Re-Saturation
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 ... En savoir plus
Modeling of Thermal Load and Electric Fields in Microfocus X-Ray Tubes
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 ... En savoir plus
Multiphysical Optimization of the Next Generation of Energy Efficient High Temperature Furnaces
To achieve the goals of the Paris Agreement and limit global warming below 2 K compared to pre-industrial level, significant energy savings in all fields of industries will be required. One example of energy intensive processes in industrial fabrication is heat treatment. The applied ... En savoir plus
Using COMSOL® in a Connected Virtual Factory -Thermal RSM for Rapid Adaptable Packaging Line
A tablet blister cavity is thermally modelled using the Shell interface in COMSOL® and a response surface created to connect to other simulations such as process flow/cost models to form a surrogate model. This virtually represents a pharmaceutical tablet packaging line, that is ... En savoir plus
Interaction of the Laser with the Material Modelling of the Micro-Lenses Creation
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 ... En savoir plus
Common Mode Choke Electromagnetic Simulation
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 ...
