英文摘要 | Appropriate simulation of air flow in porous media needs an accurate estimate of relative air permeability (RAP). Combining two traditional and two fractal water retention curves (WRCs) respectively with six permeability equations, we obtained twelve statistical and twelve fractal RAP models. All these models were subsequently tested with thirty‐one experimental datasets of disturbed soils to examine their predictive ability for RAP. Results showed that irrespective of using traditional or fractal WRCs, the six permeability equations exhibit consistent performances for RAP prediction. The modified Burdine (Yang & Mohanty, 2015) permeability equation best fits the published soil data. In addition, the selection of a proper permeability equation is critical for accurately predicting the RAP, whereas the choice of WRCs has little effect on RAP prediction. This finding suggests that for disturbed soils, air permeability is primarily dictated by the pore tortuosity‐connectivity but not the pore size distribution inferred from the WRCs. |
