straight line. The expression for the effective permeability of the networks is derived based on the parallel and series models … and the relationship between the effective permeability and the geometry structures of the network is analyzed. It is … found the effective permeability after including tortuosity is about 20% lower than that without considering the tortuosity …

expressions for seepage velocity, pressure drop, local and global permeability of the network and binary system are derived, and … the transport properties for the optimal branching structure are discussed. Notable is that the global permeability (Kn …
