Different phenomena control the performance and even selectivity in multiphase reactors. Moreover, a two way coupling between the physics could be expected when physical and/or chemical properties depend on the conversion rate. Hence, this presentation aims to show a methodology to model ... En savoir plus

High-Temperature Superconductors (HTS) can be superconducting in liquid nitrogen (77 K), holding immense promises for our future. They could enable disruptive technologies such as nuclear fusion and power applications. In a power system, for instance, high short-circuit currents can ... En savoir plus

ALD Vacuum Technologies GmbH has been using COMSOL Multiphysics® since 2020. Our machines use an electron beam system to provide the required process heat. Multiple physical aspects of this electron beam system are simulated in COMSOL Multiphysics®. Strong alternating currents run ... En savoir plus

For more than thirty years the GeePs Laboratory has been working on the numerical simulation of electromagnetic systems through numerous research topics. During this conference, we propose to present a recent problem that has been addressed by the laboratory. It is connected to ... En savoir plus

This paper presents a solution to simulate the dielectric relaxation in insulating materials using COMSOL Multiphysics in time domain. Indeed, the polarization P in a dielectric material may be divided into two parts according to the response time, the electronic polarization and the ... En savoir plus

Currently in the semiconductor industry more than 80% of silicon crystal are grown by the Czochralski (Cz) method. In this method, fused silica (SiO2) crucibles and graphite heaters are used inside furnaces. The surface of the crucibles, which are in contact with the molten silicon, is ... En savoir plus

Here we optimize the geometry: proof mass length Lm to total length L, thickness of the piezoelectric material (Tp) to total cantilever thickness (T) for obtaining the maximum stress distribution (Smax), output voltage (Vout) and power performance (Pout) of the unimorph Cantilever beam ...

Introduction Over the last years, there has been an increasing interest in plastic recycling as an alternative to reduce fossil fuel dependency. In this light, chemical recycling has been presented as a promising strategy to maximise the recycling rate, although this technology presents ... En savoir plus

Heat management has became a bottleneck in electronic engineering because of the large amount of energy released by current devices due to its extreme level of miniaturization [1]. This is a very important limitation to achieve, for example, terahertz clock-rates in computing and it is ... En savoir plus

The progress within the field of additive manufacturing has eased the fabrication of new reactor geometries significantly. It is possible to design and print a reactor of tailored shape and size at comparatively low costs and short time. Printing and testing all sensible reactor designs ... En savoir plus
