Gas Steady-state Diffusion in Fractal Porous Media [PDF]
E3S Web of Conferences, 2021 Gas diffusion in fractal pores does not follow the classic Fick’s and Knudsen’s laws, so more research on gas diffusion in fractal porous media is needed. Fractal pore models are generated using the random walk method.

Nanoconfined Bulk-Gas Transport Behavior over a Wide Range of Knudsen Number
Geofluids, 2022 Shale matrix, located at Guizhou Province, is rich in nanopores, and gas slippage takes place during shale gas development, resulting in inapplicability of the classical Navier-Stokes equation.

Simulation experiment and mathematical model analysis for shale gas diffusion in nano-scale pores
Shiyou shiyan dizhi, 2021 Gas diffusion in nano-scale porous media of deeply burried shale includes bulk diffusion (Fick and Knudsen diffusions) and surface diffusion. To reveal the migration mechanism of this process, the influence of temperature and pressure on diffusion ...

Fractal characteristics of shale pore structure and its influence on seepage flow
Royal Society Open Science, 2021 The migration law of shale gas has a significant influence on the seepage characteristics of shale, and the flow of the gas is closely related to the pore structure. To explore the influence of shale pore parameters on permeability in different diffusion
