Pore-Scale Simulation of Confined Phase Behavior with Pore Size Distribution and Its Effects on Shale Oil Production
(MDPI, 2021-02-28)Confined phase behavior plays a critical role in predicting production from shale reservoirs. In this work, a pseudo-potential lattice Boltzmann method is applied to directly model the phase equilibrium of fluids in ... -
Evaluation of Seismic Vulnerability of Hospitals in the Tehran Metropolitan Area
(MDPI, 2021-02-05)The Tehran metropolitan area is extremely vulnerable to earthquakes due to the location of its active faults and its dense population. Assessing the probable damage of a high magnitude earthquake on buildings and facilities ... -
Review and simulation of passive seismic tomography in block cave mining
(Australian Centre for Geomechanics, Perth, 2018)Seismic tomography methods are progressing in crustal seismology and at the smaller mining scale to recognise highly stressed or fracture-prone areas. Velocity variations measured by seismic tomography represent stress ... -
A conceptual protocol for integrating multiple parameters for risk assessment due to induced seismicity in a deep mine
(2020-01-01)Typically, the time-dependent b-value has been shown to decrease prior to the occurrence of a higher-magnitude event, thus providing a possible indicator of the timing of a significant event. The Energy Index relates seismic ... -
Passive Seismic Imaging of Stress Evolution with Mining-Induced Seismicity at Hard-Rock Deep Mines
(2020-06)This work aims to examine the stress redistribution with evolving seismicity rates using a passive seismic tomographic tool. We compiled a total of 26,000 events from two underground mines and partitioned them into multiple ... -
Experimental and Statistical Investigation of Reservoir Properties with the Effect of Waterflooding Treatment
(2020-08-25)An oilfield reservoir over long-term operation may have different petrophysical information, which has a significant impact on oilfield maintenance and finance. Successful oilfield enhanced oil recovery benefits a lot from ... -
Fine Bauxite Recovery Using a Plate-Packed Flotation Column
(MDPI, 2020-09-02)In this investigation, the fine-grained bauxite ore flotation was conducted in a plate-packed flotation column. This paper evaluated the effects of packing-plates on recovering fine bauxite particles and revealed the ... -
Discrimination of Six Flotation Kinetic Models Used in the Conventional Flotation and Carrier Flotation of -74 μm Coal Fines
(2020-06-16)In this study, experimental results of conventional flotation and carrier flotation were characterized by six commonly used flotation kinetic models. Two statistical criteria (coefficient of determination, R-2, and root ... -
Enhanced Bauxite Recovery Using a Flotation Column Packed with Multilayers of Medium
(MDPI, 2020-06-30)An innovative self-designed medium was packed in a bench-scale flotation column to study its influence on the flotation recovery of bauxite. Computational fluid dynamics (CFD) simulation was conducted to reveal the impact ... -
A Comprehensive Review of Rare Earth Elements Recovery from Coal-Related Materials
(MDPI, 2020-05-17)Many studies have been published in recent years focusing on the recovery of rare earth elements (REEs) from coal-related materials, including coal, coal refuse, coal mine drainage, and coal combustion byproducts particularly ... -
Effect of Pore Size Heterogeneity on Hydrocarbon Fluid Distribution, Transport, and Primary and Secondary Recovery in Nano-Porous Media
(MDPI, 2020-04-03)In this paper, we investigate the effect of pore size heterogeneity on fluid composition distribution of multicomponent-multiphase hydrocarbons and its subsequent influence on mass transfer in shale nanopores. The change ... -
Springing for Safe Water: Drinking Water Quality and Source Selection in Central Appalachian Communities
(MDPI, 2020-03-21)Issues surrounding water infrastructure, access, and quality are well documented in the Central Appalachian region of the United States. Even in cases where residents have in-home piped point-of-use (POU) water, some rely ... -
Grinding Behaviors of Components in Heterogeneous Breakage of Coals of Different Ash Contents in a Ball-and-Race Mill
(MDPI, 2020-03-03)Coals used for power plants normally have different ash contents, and the breakage of coals by the ball-and-race mill or roller mill is an energy-intensive process. Grinding phenomena in mill of power plants is complex, ... -
Differential Entropy Analysis of the Acoustic Characteristics of a Biomimetic Dynamic Sonar Emitter
(MDPI, 2020-03-03)Active noseleaf deformations during pulse emission observed in hipposiderid and rhinolophid bats have been shown to add a time dimension to the bats’ acoustic emission characteristics beyond the established dependencies ... -
Development of a Methodology for Interface Boundary Selection in the Multiscale Road Tunnel Fire Simulations
(2018-07)The simulation of large complex dynamical systems such as a fire in road tunnels is necessary but costly. Therefore, there is a crucial need to design efficient models. Coupling of computational fluid dynamics (CFD) models ... -
Dynamic Displacement of an Aluminum Frame Using Close Range Photogrammetry
(MDPI, 2019-07-29)Dynamic displacement measurement of objects can be challenging due to the limitations of conventional methods and pricey instrumentation of unconventional methods, such as laser scanners. In this research, Close Range ... -
A Review of Gas Injection in Shale Reservoirs: Enhanced Oil/Gas Recovery Approaches and Greenhouse Gas Control
(MDPI, 2019-06-19)Shale oil and gas resources contribute significantly to the energy production in the U.S. Greenhouse gas emissions come from combustion of fossil fuels from potential sources of power plants, oil refineries, and flaring ... -
Determination of critical parameters in the analysis of road tunnel fires
(Elsevier, 2018-07-12)The analysis of the fluid characteristics downstream of a fire source in transportation tunnels is one the most important factor in the emergency response, evacuation, and the rescue service studies. Some crucial parameters ... -
Method of separating and de-watering fine particles
(United States Patent and Trademark Office, 2016-12-13)A process for cleaning and dewatering hydrophobic particulate materials is presented. The process is performed in two steps: 1) agglomeration of the hydrophobic particles in a first hydrophobic liquid/aqueous mixture; ... -
Cleaning and dewatering fine coal
(United States Patent and Trademark Office, 2017-10-17)Fine coal is cleaned of its mineral matter impurities and dewatered by mixing the aqueous slurry containing both with a hydrophobic liquid, subjecting the mixture to a phase separation. The resulting hydrophobic liquid ...
