Analysis of the Coal Fluidization Mining Process with the Continuous-Discontinuous Coupled Particle-Block Method

Geofluids, 2022
In situ fluidization mining is a promising method which shows considerable potential for reducing the ecological influence impacts of coal mining. During fluidization mining, coal gangue will be separated from the ores, filled back, and returned to the ...

Hydro-micromechanical modeling of wave propagation in saturated granular media [PDF]

, 2018
Biot's theory predicts the wave velocities of a saturated poroelastic granular medium from the elastic properties, density and geometry of its dry solid matrix and the pore fluid, neglecting the interaction between constituent particles and local flow ...

Fluid-solid-thermal coupling analysis of an underwater valve

Journal of Physics: Conference Series, 2021
Abstract An underwater valve at 3000 meters underwater was chosen as the research object, aiming at obtaining the force characteristics of the underwater valve under high pressure and large temperature difference in the deep sea. The principle of fluid-solid-thermal three-field coupling was analyzed by using Fluent and ANSYS Workbench ...
