The efficiency and environmental impact of oil production become a principal challenge of energy producing companies. The improvement of existing and development of novel methods are often feasible within either a “new” physical framework (from the viewpoint of oil reservoir ... En savoir plus
INTRODUCTION: A key parameter for electrical engines is the power density. High power density is particular beneficial for traction drives. Accordingly, optimizing power density is essential for competitive ability in the Formula Student Electric racing series [1]. The operating ... En savoir plus
Plasma torches are used in processing of materials and in energy industry for producing plasma. In a non-transferred arc plasma torch, an electric arc can be glowed by applying a direct current (DC) between the cathode and anode, both placed inside the torch. Then, the plasma (Fig. 1) is ...

In inductive heating simulations the electromagnetic properties of the steel have a significant impact on the temperature pattern along the heated product. Indeed, taking into account the non-linearity of the ferromagnetic material properties is a key point to have relevant simulation ... En savoir plus
The use of microwaves for heating purposes of dielectric materials is encountered in many industrial applications (food processing, chemistry, material engineering and medical applications). In most of these thermal applications, the prediction of the temperature evolution within the ... En savoir plus
Introduction: The use of microwave energy for thermal cracking (from thermal stress and water pore pressure) of lignite-coal briquettes increases the lignite friability [1] and is beneficial for later chemical treatment inside a gasifier (for methanol production for example). An ... En savoir plus
It is well-known that metal nanoparticles (NPs) excited at the plasmon frequency not only exhibit peculiar optical properties (e.g., a peak in the extinction spectrum, an enhanced electromagnetic near-filed) but also heat up [1]. This phenomenon is highly investigated for medical ... En savoir plus
Resistive heating filaments used in high temperature applications at 2000°C and above are often made of refractory metals. The lifetime of such filaments is mainly limited by creep deformations which can in the worst case lead to a short circuit between filaments and other furnace ... En savoir plus
In this paper, we present a 2D axisymmetric self-consistent plasma fluid model for microwave plasmas operating in argon. The model was developed using COMSOL Multiphysics and its Plasma Module. Plasma, flow, heat and electromagnetic equations solved self-consistently. The effect of the ... En savoir plus
The design of ESS-Bilbao RFQ (RadioFrequency Quadrupole) linear accelerator cavity using COMSOL Multiphysics is presented. The work includes geometry definition, electrostatics, electromagnetic and thermomechanical coupled simulations. The main part of the work corresponds to the ... En savoir plus
