Geothermal characterization of the coastal aquifer near Ravenna (Italy)

Acque Sotterranee, 2012
The coastal aquifer near Ravenna (Italy) contains a large volume of groundwater (2,5x109 m3) whose quality has been compromised by sea-water intrusion. Today, the phreatic groundwater is mostly brackish with some lenses of freshwater floating on top of ...

In Situ CO2‐Induced Hydrogels for Enhancing Carbon Sequestration in Saline Aquifers

Advanced Science, EarlyView.
A novel integrated method that combines in situ CO2‐induced phase‐transition hydrogels formed by a C22‐tailed tertiary amine dispersion with tailored deep eutectic solvents to increase CO2 sequestration in saline aquifers. ABSTRACT Carbon sequestration in saline aquifers underpins global net‑zero emission goals, yet existing CO2 storage capacity ...

Radiative Hybrid Nanofluid Flow Over a Porous Riga Surface: A Fuzzy–ANN Modeling Approach

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT This study proposes a fuzzy–ANN model to investigate the nonlinear thermal transport in a tangent hyperbolic (Tanh) hybrid nanofluid flow past a porous Riga surface, considering the effects of Rosseland diffusion, chemical reactions, and internal volumetric heating.

The Use of Renewable Energy in Prominent City Buildings: A Diffusion Study on Top European Football Organizations

Business Strategy and the Environment, EarlyView.
ABSTRACT The present study applied the diffusion of innovation theory to investigate the rate of diffusion of renewable energy sources used by Europe's top professional football stadiums and the relationship with carbon neutrality. A discrete diffusion model estimated the diffusion of renewable energy to saturation, and a multivariate logistic ...

Bridging the Gap Between Earth Sciences and Mechanical Engineering: A Systematic Approach to Model Ground Source Heat Pumps with Deep Boreholes

Energies
Modelling of geothermal heat pump systems rarely integrates detailed surface and subsurface components. Simplifications such as neglecting the geothermal gradient, the different geological units intersected by the systems, and/or variable building loads,
