Pasteurisation and sterilisation are crucial thermal processes for insuring microbiological safety and stability of foods. In the food industry, microwave (MW) heating enables treatment of food products in their final packaging, thus limiting post-process recontamination. During the ... En savoir plus

In this work, a novel approach is presented for analyzing the structure of a high-frequency integrated inductor–inductor–capacitor (LLC) resonant transformer through multiphysical simulation. The objective is to create a digital twin of the LLC transformer that closely resembles an ... En savoir plus

Reactive transport modelling in subsurface environments, such as geological disposal of radioactive waste, often requires complex coupling between transport phenomena and geochemical reactions. Traditionally, this coupling requires third-party tools such as iCP to link multiphysics ... En savoir plus

Gallium nitride (GaN) power modules are increasingly adopted in applications such as electric vehicle on-board chargers, due to their lower power loss and higher switching speed. To enhance power density and reduce parasitic inductance, modern packaging solutions are being developed ... En savoir plus

The use of advanced manufacturing technologies expands the design scope of lightweight components for aerospace systems and enables innovative possibilities for complex structures [1, 2]. The overall approach of the AdHyBau (Additive Hybrid Construction) joint project is to develop new ... En savoir plus

Power-to-gas is an important area of research for reducing greenhouse gases and seasonal energy storage. Methane, with a Lower Heating Value of 50 MJ/kg, is already a commonly used gas, and its synthesis using green hydrogen production (electrolysis of renewable energy) is a remarkable ...

The transport sector is one of the largest emitters of climate-effecting emissions. Thus, a major transformation in this sector is necessary to achieve Germanys and EUs ambitious goals of CO2 neutrality. In these transitions, fossil fuel-based engines will be replaced by sustainable ... En savoir plus

Stray light represents a significant challenge in a wide range of photodiode and photodiode array applications, as it elevates the background signal, reduces detector sensitivity, and degrades the signal-to-noise ratio. Traditional approaches to mitigate stray light, such as blackening ... En savoir plus

This work presents a comprehensive modeling and validation study of MEMS-based infrared (IR) emitter chips using a neural network-assisted inverse modeling approach in COMSOL Multiphysics. Starting from a single baseline chip geometry, a simulation model was developed that captures the ... En savoir plus

This study presents a model for simulating a subsurface pumped-hydro energy storage (battery) system. The model captures the coupling between fluid flow in an oil and gas type wellbore connected to a large hydraulic fracture embedded in a low-permeability reservoir. By integrating ... En savoir plus
