Pipeline inspection tools present some limitations related to power supply which require recharging after each operation. Using batteries or tethered tools make the duration to inspect any pipeline very limited and time consuming. This paper aims at designing a spherical self-recharging ... En savoir plus
Brain-Machine Interfaces (BMI) provide a direct communication link between brain and external devices such as speech synthesizers and robotic prosthesis to restore speech and movement in persons affected by Spinal Cord Injuries or neurodegenerative diseases such as Amyotrophic Lateral ...

The EPFLoop team from Ecole Polytechnique Fédérale de Lausanne has developed a capsule thanks to which it won the 3rd place in SpaceX’s Hyperloop Pod Competition in 2018. This year the EPFLoop team has been selected again to participate at the 2019 Competition held at the SpaceX ... En savoir plus
Introduction: Vibration energy harvester can convert mechanical vibration energy into electrical energy and store it in battery for later use. It can create clean renewable energy from vibration movements such as walking, jumping, running, etc. This can convert energy previously wasted ... En savoir plus
In this study fluid-dynamical and thermal performance of active chilled beams is investigated by 2D and 3D modelling in COMSOL Multiphysics. Three different typologies of those air conditioning systems are considered. Results, obtained for typical range of variation of operational ... En savoir plus

Herein, we present results ... En savoir plus
At Leoni, we are not only working towards even more reliable, performant cables by simulating their electric, magnetic, mechanical as well as thermal properties but also bring our customer applications to our design board. Based, amongst others on multi-physical simulations, we prepare ... En savoir plus
A thermo-physical 3D model of a commercial Li-ion battery was developed and validated. Visualization of the temperature distributions inside a Li-ion cell during cell stacking processes were simulated. Critical temperature levels depend on position, duration and intensity of the thermal ... En savoir plus
环境污染问题日益严重，新能源汽车将逐渐成为汽车工业发展的新方向，而动力电池作为整个电动汽车的驱动核心，其安全性和使用寿命受到广泛关注。动力电池组在大倍率充放电时内部化学反应加剧，各单体电池温度急剧升高，电池单体之间的不一致性加剧，容易引发热失控等一系列安全事故。本工作采用COMSOL Multiphysics有限元软件对圆柱卷绕式锂离子电池建立3D电化学-热平均耦合有限元模型，将电化学模型与热模型结合分析电池的电化学特性以及热行为，最终建立一个安全可靠的热管理系统。 首先使用COMSOL软件的“电池与燃料电池模块”和“传热模块”这两个模块和“锂离子电池接口” ...
