A novel construction approach for the pore structure model principally focuses on the controllable roundness of rock particles

open access: yesDeep Underground Science and Engineering, EarlyView.
Particle rounding effects comparison of different methods: (a), (b), and (c) are the rounding results using the B‐spline curve method with different R; (d), (e), and (f) are the results of vertex rounding substitution method with different rounding radii.

Axisymmetric flow model of cannabis oil extraction of supercritical fluid extraction CO2 process

open access: yesInternational Journal of Thermofluids
Supercritical fluid extraction using CO2 is a widely recognized method for purifying oil extracts. Understanding the extraction process is important for improving yields. While most research has focused on one-dimensional simulations, there is a need for

CO2 injection into submarine sediments: disturbing news for methane-rich hydrates [PDF]

open access: yes, 2011
The production of natural gas via injection of fossil-fuel derived CO2 into submarine gas hydrate reservoirs can be an example of tapping a hydrocarbon energy source in a CO2-neutral manner.

Challenges, models, and algorithms for flow and transport simulations in deep reservoirs

open access: yesDeep Underground Science and Engineering, EarlyView.
Deep reservoirs are considered a promising resource for future energy supply, but current reservoir simulation technologies may face certain challenges if they are directly used in specific scenarios in deep reservoir development. Models and algorithms were developed to resolve these challenges, including a better phase equilibrium model, a better ...

Multiphysics modeling of coupling compressed‐air energy storage‐thermal storage in salt caverns: An approach to insoluble sediment as heat reservoir feasibility analysis

open access: yesDeep Underground Science and Engineering, EarlyView.
This study investigates the feasibility of utilizing insoluble sediments in salt caverns for short‐ and long‐term thermal energy storage applications. The analysis revealed three key thermal characteristics of these sediments: (1) thermal shock resistance, (2) temperature differential compensation capability during air injection, and (3) high ...
