"The book comprises an assembly of benchmarks and examples for porous media mechanics collected over the last twenty years. Analysis of thermo-hydro-mechanical-chemical (THMC) processes is essential to many applications in environmental engineering, such as geological waste deposition, geothermal energy utilisation, carbon capture and storage, water resources management, hydrology, even climate chance. In order to assess the feasibility as well as the safety of geotechnical applications, process-based modelling is the only tool to put numbers, i.e. to quantify future scenarios. This charges a huge responsibility concerning the reliability of computational tools. Benchmarking is an appropriate methodology to verify the quality of modelling tools based on best practices. Moreover, benchmarking and code comparison foster community efforts. The benchmark book is part of the OpenGeoSys initiative, an open source project to share knowledge and experience in environmental analysis and scientific computation."

"This monograph presents an integrated perspective of the wide range of phenomena and processes applicable to the study of transport of species in porous materials. In order to formulate the entire range of porous media and their uses, this book gives the basics of continuum mechanics, thermodynamics, seepage and consolidation and diffusion, including multiscale homogenization methods. The particular structure of the book has been chosen because it is essential to be aware of the true properties of porous materials particularly in terms of nano, micro and macro mechanisms. "

"This short book deals with the mathematical modeling of jets impinging porous media. It starts with a short introduction to models describing turbulences in porous media as well as turbulent heat transfer. In its main part, the book presents the heat transfer of impinging jets using a local and a non-local thermal equilibrium approach.

"This research was carried out with the aim of providing a better understanding of the multiphase fluid flow characteristics of fluid-rock systems during the geo-sequestration process. The ultimate goal of this research was to experimentally evaluate the change in a number of multiphase flow characteristics of the system over time caused by the potential chemical and physical/mechanical processes occurring during deep CO2 disposal. In order to achieve this goal the effects of cyclic/alternating CO2-brine flooding, flow direction, existence of residual hydrocarbon (natural gas) and change in the reservoir stress field on the system’s multiphase flow behaviour were investigated.

Chen, Zhangxin, 1962-
"This book offers a fundamental and practical introduction to the use of computational methods, particularly finite element methods, in the simulation of fluid flows in porous media. It is the first book to cover a wide variety of flows, including single-phase, two-phase, black oil, volatile, compositional, nonisothermal, and chemical compositional flows in both ordinary porous and fractured porous media. In addition, a range of computational methods are used, and benchmark problems of nine comparative solution projects organized by the Society of Petroleum Engineers are presented for the first time in book form.
Computational Methods for Multiphase Flows in Porous Media reviews multiphase flow equations and computational methods to introduce basic terminologies and notation. A thorough discussion of practical aspects of the subjects is presented in a consistent manner, and the level of treatment is rigorous without being unnecessarily abstract. Each chapter ends with bibliographic information and exercises."

"Mixed matrix membranes (MMMs) adalah material komposit yang terbuat dari polimer yang terisi dengan material pengisi. MMM digunakan secara luas dalam proses pemisahan gas, seperti memisahkan CO2 dari N2. Namun, MMM yang dimuat dengan padatan berpori diketahui memiliki trade-off permeabilitas-selektivitas, yang berarti, peningkatan permeabilitas gas pada membran menyebabkan selektivitas gas yang lebih rendah. Para peneliti menemukan cara untuk meningkatkan kinerja MMM. Tujuan dari proyek ini adalah untuk menyelidiki potensi kelebihan dari MMM berbasis poly(vinyl) alcohol (PVA) dan polymer of intrinsic microporosity (PIM-1) yang dimuat dengan cairan berpori dibandingkan dengan MMM yang dimuat padatan berpori dan membran murni. Aglomerasi MMM, permeabilitas CO2, dan selektivitas CO2/N2 diamati melalui uji karakterisasi menggunakan XRD, FTIR, dan TGA. Uji selektivitas dan permeabilitas dilakukan menggunakan welded gas rig. Lima bahan padat berpori (UiO-66-OH, phloroglucinol-based porous organic framework (POF), SNW-1, Aluminium Fumarate (AlFum) dan hollow silica (HS)) diimplementasikan untuk menjadi pengisi membran. Melalui uji karakterisasi (XRD, FTIR, TGA, SEM, DSC, BET, dan Pycnometer) dan pertimbangan model prediksi IAST, padatan berpori yang paling cocok dicairkan dan dimuat ke dalam membran. Hasillnya, MMM cair berpori mengalami pengurangan signifikan dalam aglomerasi, peningkatan permeabilitas CO2 dan peningkatan selektivitas CO2/N2 dibandingkan dengan membran murni dan MMM padat berpori. Temuan ini menegaskan keuntungan dari MMM cair berpori dalam pemisahan gas.

Mixed matrix membranes (MMMs) are composite materials made by embedding polymer with filler substances, and they are commonly used in gas separation processes, such as CO2 removal from N2. However, MMMs that contain porous solids typically exhibit a trade-off between permeability and selectivity, where increasing gas permeability reduces the membrane’s ability to selectively separate gases. To enhance the performance of MMMs, researchers are exploring different approaches. This project aims to examine the benefits of MMMs made from poly(vinyl) alcohol (PVA) and polymer of intrinsic microporosity (PIM-1), which are loaded with porous liquids, compared to MMMs loaded with porous solids and neat membranes. The study evaluates membrane agglomeration, CO2 permeability, and CO2/N2 selectivity through characterization methods like XRD, FTIR, and TGA, along with performance testing using a welded gas rig. The fillers used in the membranes include five porous solid materials: UiO-66-OH, a phloroglucinol-based porous organic framework (POF), SNW-1, Aluminium Fumarate (AlFum), and hollow silica (HS). By conducting various tests (XRD, FTIR, TGA, SEM, DSC, BET, and pycnometer) and considering the IAST prediction model, the most suitable porous solid is then liquefied and incorporated into the membrane. The results show that the use of porous liquids in MMMs reduces agglomeration and significantly improves CO2 permeability and CO2/N2 selectivity compared to MMMs containing porous solids and neat membranes. These findings highlight the potential advantages of porous liquid MMMs for gas separation applications."
