Thermoelectric power generation has been envisioned as a clean energy alternative to conventional thermal to electric power generation for decades due to its noiseless and low-cost operation. However, a typical thermoelectric generator suffers from low device efficiency, so it has been a ... En savoir plus

A new microwave cavity for the regeneration of DPF regeneration was proposed and COMSOL Multiphysics® FEM model was used to investigate heating properties of the Silicon Carbide (SiC) based DPF. Electric field profile and thermal profile of the microwave cavity and DPF was established ... En savoir plus

Radio-Frequency ablation (RFA) has received a considerable interest as a minimally invasive treatment technique used for destruction of a variety of primary and metastatic hepatic tumors. A parametric study of hepatic radio-frequency ablation using three-dimensional numerical models has ... En savoir plus

In this work, a methodology is developed, based on the application of finite element method in the frequency domain, using the COMSOL Multiphyics software, aiming the sensibility analysis of inductance calculation involving some configurations of an E-core magnetic circuit. Such ... En savoir plus

High Voltage Direct Current transmission (HVDC) is a suitable alternative for long distance transmission. During the years, the use of this technology has been increasing, which is one of the several reasons to improve methodologies in HVDC grounding systems. Unlike the usual approach ... En savoir plus

When an electronic device is worn for extended periods, possibly in direct contact with human skin, heat must be safely transferred away from the device, without exceeding standards and regulatory temperature limits on the skin and on the exposed surfaces of the device. Heat transfer is ... En savoir plus

The reduction of energy consumption in the building sector (nearly 40% of the energy consumption in Europe) is a real challenge to achieve the objective of the “2020 European climate and energy package”. In recent years, great interest is observed for the Stirling thermoacoustic ... En savoir plus

This paper is a preliminary design study to develop a hybrid atmospheric icing sensor which have an adequate potential to detect an icing event, icing type and icing rate together with icing load. The physics to detect icing event and icing type have been numerically understood using ... En savoir plus

GalFeNol is a new Giant Magnetostrictive Material that can be used in energy harvesting especially in vibration reduction applications, thanks to the Joule and Villari effects. A 3D-model of GalFeNol rod is stressed by a time varying longitudinal force of 1000 N. The study has been ... En savoir plus

Plasma Arc Welding (PAW) is one of the important arc welding processes commonly used in electronics, medical, automotive and aerospace industries due its high accuracy, finishing, and ability of welding any hard materials. It is an extension of Tungsten Inert Gas welding (TIG or GTAW). ... En savoir plus
