COMSOL Multiphysics® and the Batteries & Fuel Cells Module are used to create a pseudo 2D model of a Li-ion battery. A sensitivity analysis determines the most sensitive model parameters which are identified by microstructure analysis or optimized by nonlinear least-square regression ... En savoir plus
Photovoltaic-powered electrolysis (PV-EC) though the most mature technology for zero-carbon integrated solar to hydrogen conversion, is still only approaching industrial and commercial relevance, and devices with light absorber area larger than 100 cm2 are quite rare [1,2]. Here, we ... En savoir plus
In order to optimize the industrial “ammunition cooling” process, a COMSOL Multiphysics® model is proposed. A shell body filled with a melt-cast explosive formulation is poured and cooled by circulation of a heat transfer fluid. The solidification of the explosive composition has several ... En savoir plus
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 ...
