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

Geothermal energy systems require precise sizing to ensure efficiency and sustainability, particularly for probe fields and groundwater doublets. We present two specialized applications developed using COMSOL Multiphysics’ Application Builder, leveraging the Heat Transfer and Groundwater ... En savoir plus

Bitumen and asphalt durability is a critical concern in pavement engineering, particularly in the context of sustainability and carbon footprint reduction. Accurate prediction of the lifespan of these materials is essential for life cycle assessment (LCA) from cradle to grave. However, ... En savoir plus

As the global energy transition accelerates, large-scale seasonal thermal energy storage systems are becoming critical components of future sustainable and resilient district heating networks. Among various storage technologies, cavern thermal energy storage (CTES) offers a promising ... 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

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

The integration of machine learning (ML) techniques into geophysical exploration and underwater mapping has emerged as a transformative approach for interpreting complex sensor data. This paper presents a comprehensive framework for using COMSOL Multiphysics to develop and validate ... En savoir plus

Soil sedimentation and consolidation, whether they are naturally or anthropically driven processes, are closely interconnected. While theoretical models are available to separately describe the behaviour of either ‘fluid’ suspensions or ‘solid’ soil, no well-established unified theory ... En savoir plus

Multi-parameter monitoring techniques, combined with robust mathematical models, are crucial for effective volcano monitoring and early warning to civil authorities and the public. This work focuses on the modeling of ground deformation, an indispensable component for any volcano ... En savoir plus

Increased concentrations of greenhouse gases in the atmosphere are known to be the main cause of global warming. Among the various decarbonisation strategies proposed, geological storage of CO2 is one of the most interesting options for reducing net carbon emissions to the atmosphere. ... En savoir plus
