We analyze the possibility of describing the quenched, disordered characteristics of complex porous matrices by means of local pointwise functions (local accessibility and local porosity fields). Detailed numerical results are developed for 2-d percolation clusters. It is shown that, even far from criticality, percolation clusters exhibit an highly heterogeneous structure of the local accessibility function. The connection between quenched disorder in porous media and dynamic disorder of turbulent flow is discussed.

Abstract
We analyze the possibility of describing the quenched, disordered characteristics of complex porous matrices by means of local pointwise functions (local accessibility and local porosity fields). Detailed numerical results are developed for 2-d percolation clusters. It is shown that, even far from criticality, percolation clusters exhibit an highly heterogeneous structure of the local accessibility function. The connection between quenched disorder in porous media and dynamic disorder of turbulent flow is discussed.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
