摘要
Abstract
Based on the fractal theory and Monte Carlo algorithm,a two-dimensional random porous media is established,and the 4-neighbourhood seed-filling algorithm is used to analyze the seepage performance of the porous media.Results show that the percolation threshold is about 0.593.Three porosities are selected to statistically analyze of the clusters in the model.The cluster number curve is relatively smooth when n=50.The probability distribution curve of the clusters is negatively correlated with the cluster size before the percolation behavior of the two-dimensional porous media.The largest cluster percentage has a scale invariance.While the dead-end cluster size presents a similar characteristic of the normal distribution.As porosity increases,the permeability of random porous media also increases,whereas the tortuosity decreases.关键词
