Analysis of permeability and percolation properties of systems of solid rectangular particles by computer simulation method

A 2D porous medium containing solid rectangular particles has been investigated using the computer simulation method. We have used the model of nonintersecting rectangles on a square lattice. An analysis of the effect of area, linear sizes, and degree of orientation of rectangles on the percolation of pores and particles of the system has been carried out for different methods of lattice filling. The resulting dependences have been compared and an explanation of the observed effects has been proposed.
