Electrolytic hydrogen production stands as a beacon of promise within the realm of sustainable energy technologies, owing to its remarkable potential for yielding hydrogen with high energy efficiency and enabling long-term energy storage. Among the gamut of hydrogen production ... En savoir plus

Liquid atomization relies on a variety of forces that disturb the surface of the liquid. In the case of flow-blurring (FB) atomization, turbulent structures are induced within the liquid channel to achieve this effect. It is known that the transition from the conventional flow-focusing ... En savoir plus

An attempt is made to study the gaseous flow in Resistive Plate chambers(RPCs)- A gaseous detector used in experimental physics for detection of particle behaviours. The present study is based on two phase laminar flow analysed through two methods(conservative Level-Set and Phase field ... En savoir plus

The aim of the present work is to implement in COMSOL Multiphysics a multiphase fluid flow model in porous media, also known in the oil reservoir engineering literature as a black oil model, using a standard finite element approach. In particular, we are interested to apply this model ... En savoir plus

The release of hydrogen from Liquid Organic Hydrogen Carriers (LOHC) is a highly volume-expanding, multiphase reaction with a high heat demand [1]. Platinum on porous alumina support is used as the catalyst for dehydrogenation. Since reactor design requires a deep understanding of the ... En savoir plus

Renewable energies generate temporary mismatches between energy demand and supply. The conversion of surplus energy to hydrogen and its storage in geological formations is one option to balance this energy gap. Storage in deep saline aquifers is the most cost-effective option for ... En savoir plus

Campi Flegrei (CF) is the largest active urbanized caldera in Europe, currently experiencing slow but progressive ground uplift and increasing seismicity since 2005. This deformation is marked by transient variations in uplift rates, with monotonic episodes lasting weeks to years. In ... En savoir plus

Porous three-dimensional electrodes are promising for use in alkaline electrolyzer due to their high surface area. Nickel foams, specifically, serve a dual purpose as both a current collector and an active working electrode, enhancing current density and boosting hydrogen production[1]. ... En savoir plus

Nowadays, gas and nuclear waste storage, shale gas and EOR exploitation rise the need to understand and predict the fate of multiphase flows in the underground. Various formulations for multiphase flow arise from different linear combinations of governing equations and choice of ... En savoir plus

Introduction The COMSOL Multiphysics® software and its CFD Module have a physics interface for solving Laminar Two-Phase Flow problems using the Level Set method (1). This paper discusses how the tool may be used with more than two phases when the flow is laminar. It then introduces a ... En savoir plus
