Predicting Ecosystem Net Primary Productivity by Percolation Theory and Optimality Principle Allen G. Hunt, Muhammad Sahimi, Behzad Ghanbarian, and German Poveda The water balance equation divides precipitation at the Earth’s terrestrial surface into its two principal pathways: evapotranspiration (ET) and run-off (Q). Known as the “central problem of hydrology,” since Robert Horton declared that in

Effect of Reservoir Heterogeneity on Well Placement Prediction in CO2-EOR Projects Using Machine Learning Surrogate Models: Benchmarking of Boosting-Based Algorithms T. Esfandi, S. Sadeghnejad, A. Jafari Carbon capture and storage (CCS) during enhanced oil recovery (EOR) in underground reservoirs offer both environmental and economic benefits. This study explores the efficiency of five machine learning boosting

Unveiling Moisture Transport Mechanisms in Cellulosic Materials: Vapor vs. Bound Water Y. Zou, B. Maillet, L. Brochard, P. Coussot   Natural textiles, wood, hair, paper, wool, or bio-based walls possess the remarkable ability to store humidity from sweat or the environment through “bound water” absorption within nanopores, constituting up to 30% of their dry mass.

Compaction and Clay Content Control Mudrock Porosity A. Rezaeyan, N. Kampman, V. Pipich, L. C. Barnsley, G. Rother, C. Magill, J. Ma, A. Busch Mudrocks, ubiquitous yet poorly understood sedimentary rocks with significant variations in pore structure, form seals for geological carbon dioxide and energy storage, repositories for radioactive waste disposal, and reservoirs for natural

Tortuosity and Microstructure Effects in Porous Media: Classical Theories, Empirical Data, and Modern Methods Lorenz Holzer, Philip Marmet, Mathias Fingerle, Andreas Wiegmann, Matthias Neumann, Volker Schmidt Empirical data shows that the tortuosity-value of a certain microstructure is more strongly dependent on the type of tortuosity than on the microstructure itself. To clarify the discussion on

Unified Flash Calculations With Isenthalpic and Isochoric Constraints V. Lipovac, O. Duran, E. Keilegavlen, F. A. Radu, I. Berre Simulation of multiphase multicomponent flow with phase change demands great flexibility, efficiency, and compatibility of the thermodynamic subproblem. Complex phenomena in the subsurface require models for multiple properties of the fluid, including volume, enthalpy, or internal

Nanothermodynamics: Theory and Applications Dick Bedeaux, Signe Kjelstrup, Sondre K. Schnell This book explains and applies the systematic thermodynamic theory of small systems proposed by Hill. It uses and extends his method. The basic ideas of the theory are highlighted, and the power of the theory in and away from equilibrium is demonstrated in several

Design Considerations for Dynamic Fluid Flow in Porous Media Experiments Using X-Ray Computed Micro Tomography T. Pak, N. Lopes Archilha, S. Berg, I. B. Butler X-ray micro computed tomography (µCT) has become an advanced non-destructive tool to analyse the internal structure of opaque materials such as porous media. The range of accessible spatial and temporal
