Modeling and experiment for effective diffusion coefficient of gas in water-saturated coal

, 2021
The diffusion of gas in water-saturated porous media plays a significant role in CO2 geological sequestration and mine gas prevention and control. However, it is lack of an accurate model to calculate the effective diffusion coefficient of gas in a water-

Gas diffusion coefficient estimation of coal: A dimensionless numerical method and its experimental validation

, 2020
The diffusion coefficient is one of the key parameters to control gas desorption and transport kinetics in coal with pressure evolution. Accurate estimation of diffusion coefficient of coal is of great significance for coalbed methane production planning

Estimation and modeling of pressure-dependent gas diffusion coefficient for coal: A fractal theory-based approach

Fuel, 2019
Diffusion coefficient is one of the key parameters determining the coalbed methane (CBM) reservoir economic viability for exploitation. Diffusion coefficient of coal matrix controls the long-term late production performance for CBM wells as it determines

Quantification of concrete chloride diffusion coefficient – A critical review

Cement & Concrete Composites, 2019
Most concrete deterioration mechanisms are driven by the transport properties, in particular the chloride diffusion coefficient. As such, experimental and analytical tools have been developed to quantify the chloride diffusion coefficient.

Diffusion coefficients of retinoids

Current Eye Research, 2002
Diffusion coefficients of various retinoids have not been measured previously. It is important to know the diffusion coefficients of the retinoids because this property might be rate-limiting in dark adaptation. Also, retinoid diffusion is important to explore given that rhodopsin regeneration is not impaired in IRBP knockout mice.Measurements of ...
