The influence of gravity on the fractal model of imbibition in rough pores considering shape factor
Aiming at the spontaneous imbibition process in irregular rough pores, a fractal model of fluid imbibition into irregular rough pores without gravity and under gravity is established in this paper. The expressions of imbibition height and imbibition mass in irregular rough pores are derived. Then, the effects of relative roughness, gravity factor, fractal dimension, shape factor and other physical quantities on the imbibition process were discussed by sensitivity analysis. The imbibition mass of fluid in irregular rough pores is negatively correlated with relative roughness, and positively correlated with physical quantities such as shape factor, radius ratio and porosity. Moreover, it is found that the average imbibition mass in rough pores with relative roughness of ε0 = 0.1 is 10.1 % lower than that in smooth pores, and 4.4 % higher than the experimental data, indicating that the imbibition mass in rough pores is more consistent with the experimental data.
