Abstract

Spontaneous imbibition plays a signiﬁcant role in different technical applications, and several analytical models have been proposed for predicting the ﬂuid imbibition mass into porous media based on the fractal theory. Herein, these previous models are reconsidered in view of the obvious difference between the effective porosity and the areal porosity of porous media. Firstly, an implicit equation for fractal tortuosity is proposed and a modiﬁed correlation for the areal porosity is presented; then, a semi-analytical prediction model for ﬂuid imbibition mass with gravity pressure is derived; ﬁnally, comparisons of predictions among several previous models with the present model are carried out. The modeling results show consistency with the experimental data published in the literature. Cited as: Li, Y., Yu, D., Niu, B.

基于修正孔隙度相关性的分形多孔介质自吸预测

自发吸积在不同的技术应用中发挥着重要的作用，基于分形理论提出了几种预测流体在多孔介质中的吸积的分析模型。鉴于多孔介质的有效孔隙率与面孔隙率存在明显差异，本文对上述模型进行了重新考虑。首先，提出了分形弯曲度的隐式方程，并提出了面孔隙度的修正关系式;在此基础上，推导了流体吸胀质量随重力压力的半解析预测模型;最后，将几种模型的预测结果与本模型进行了比较。模拟结果与文献中发表的实验数据一致。引用本文:李勇，于东，牛波。基于修正孔隙度相关性的分形多孔介质自吸预测。毛细管学，2021,4(1):13-22,doi: 10.46690/capi.2021.01.02
