Mathematical Model for Effective Gas Diffusion Coefficient in Multi-scale Fractal Porous Media [PDF]
E3S Web of Conferences, 2021 Based on the capillary hypothesis and fractal theory, a mathematical model for calculating the effective gas diffusion coefficient in porous media is established. By using fractal geometry theory, pore area fractal dimension, tortuosity fractal dimension

Effect of Modification on the Fluid Diffusion Coefficient in Silica Nanochannels [PDF]
Molecules, 2021 The diffusion behavior of fluid water in nanochannels with hydroxylation of silica gel and silanization of different modified chain lengths was simulated by the equilibrium molecular dynamics method. The diffusion coefficient of fluid water was calculated by the Einstein method and the Green–Kubo method, so as to analyze the change rule between the ...

Effective diffusion coefficients in reaction-diffusion systems with anomalous transport [PDF]
Physical Review E, 2019 We show that the Turing patterns in reaction systems with subdiffusion can be replicated in an effective system with Markovian cross-diffusion. The effective system has the same Turing instability as the original system, and the same patterns. If particles are short-lived, the transient dynamics are captured as well.

Cross-property connections between Young's modulus and diffusion coefficient of two-phase composite
St. Petersburg Polytechnical University Journal: Physics and Mathematics, 2021 The paper interrelates changes in the effective elastic and diffusion properties of a two-phase composite caused by inhomogeneities. The correlation is based on similarities between the microstructural parameters in whose terms the effective properties ...
