Global Challenges, 2023 The spread of emitted potentially virus‐laden aerosol particles is known to be highly dependent on whether a mask is worn by an infected person and on the emission scenario, i.e., whether the person is coughing, speaking, or breathing.

Physical Review E, 2004 We address the surface tension-driven dynamics of porous media in nearly saturated pore-space solutions. We linearize this dynamics in the reaction-limited regime near its fixed points -- surfaces of constant mean curvature (CMC surfaces). We prove that the only stable interface for this dynamics is the plane, and estimate the time scale for a CMC ...

Research on Stress Sensitivity of Fractured Carbonate Reservoirs Based on CT Technology
Energies, 2017 Fracture aperture change under stress has long been considered as one of primary causes of stress sensitivity of fractured gas reservoirs. However, little is known about the evolution of the morphology of fracture apertures on flow property in loading ...

Direct Visualization of Nanoscale Salt Precipitation and Dissolution Dynamics during CO2 Injection
Energies, 2022 CO2 injection to enhance shale oil recovery provides a win-win solution to meet the global fuel shortage and realize ultimate carbon neutrality. When shale reservoirs contain high salinity water, CO2 injection can result in salt precipitation to block ...

A Pore-Scale Investigation of Residual Oil Distributions and Enhanced Oil Recovery Methods
Energies, 2019 Water flooding is an economic method commonly used in secondary recovery, but a large quantity of crude oil is still trapped in reservoirs after water flooding.

The Influence of Micro-Fractures on the Flow in Tight Oil Reservoirs Based on Pore-Network Models
Energies, 2019 In this paper, the influence of micro-fractures on the flow of tight reservoirs is studied on the microscopic scale. Three-dimensional digital cores of fractured tight sandstone with varying fracture apertures, lengths, and dip angles are constructed ...

Analysis of Thermal Performances in a Ventilated Room Using LBM-MRT: Effect of a Porous Separation
Computation, 2022 This article demonstrates the feasibility of porous separation on the performance of displacement ventilation in a rectangular enclosure. A jet of fresh air enters the cavity through an opening at the bottom of the left wall and exits through an opening ...

Adjoint-based topology optimization of filter structures for gas–particle systems
AIP Advances, 2021 Conventional filters for aerosol particle deposition consist of one or more filter layers, which are either woven or composed of tangled fibers. The quality of the separation results almost exclusively from the density of the fiber arrangement.

Innovative heat pipes and thermosyphons for renewable sources of energy application
E3S Web of Conferences, 2018 In the paper the authors present possibilities of use two-phase heat-conducting devices at cooling technologies for PV and PV/T solar cooling and air-conditioning. Three ways to improve heat conductive properties of heat pipes and thermosyphons with help
