Dr. Liang Luo and associate prof. Jianchao Cai, a renowned researcher on fractal and capillarity and guest chief editor of FRACTALS, have published their latest paper entitled Numerical simulation of tortuosity for fluid flow in two-dimensional pore fractal models of porous media.
The tortuosity of different generations of Sierpinski carpet is calculated and analyzed by the finite volume method. A simple linear relation between the generations and tortuosity in pore fractal model of porous media is obtained. The results show a more realistic tortuosity predication for fluid flow in the two-dimensional pore fractal models of porous media.
The understanding of transport properties in porous media is the foundation for environmental and industrial processes covering a broad range of fields such as oil recovery engineering, civil engineering, groundwater engineering, engineering geology, soil sciences, and building materials.
