Abstract

In this paper, the fractal theory is used to consider the roughness of the matrix pore surface based on the previous research, the relative roughness model of the matrix pore surface is established, and the fractal model of anisotropic interporosity flow function and shape factor considering the relative roughness, tortuosity, and starting pressure of matrix pore is derived. The influence of relative roughness on the interporosity flow function and shape factor is also analyzed. It is found that the relative roughness is inversely proportional to the interporosity flow function but proportional to the shape factor. In addition, the rationality of the model is verified by comparing with the existing research.

粗裂双孔介质孔隙间流动函数及形状因子的分形研究

本文在前人研究的基础上，利用分形理论考虑基质孔隙表面粗糙度，建立了基质孔隙表面相对粗糙度模型，推导了考虑基质孔隙相对粗糙度、弯曲度和启动压力的各向异性孔隙间流动函数和形状因子的分形模型。分析了相对粗糙度对孔隙间流动函数和形状因子的影响。发现相对粗糙度与孔隙间流动函数成反比，而与形状因子成正比。此外，通过与已有研究的对比，验证了模型的合理性。

期刊介绍： Chemical engineering enables the transformation of natural resources and energy into useful products for society. It draws on and applies natural sciences, mathematics and economics, and has developed fundamental engineering science that underpins the discipline. Chemical Engineering Science (CES) has been publishing papers on the fundamentals of chemical engineering since 1951. CES is the platform where the most significant advances in the discipline have ever since been published. Chemical Engineering Science has accompanied and sustained chemical engineering through its development into the vibrant and broad scientific discipline it is today.
