TRANSPORT IN POROUS MEDIA
Resumen
A MONTE CARLO (MC) ALGORITHM TO GENERATE PORE NETWORKS WITH SPATIAL CORRELATION OF PORE SIZES IS DEVELOPED. THE ALGORITHM IS ILLUSTRATED FOR MODEL POROUS MEDIA DESCRIBED AS A TWO-DIMENSIONAL SQUARE LATTICES OF NODES AND BONDS WHICH REPRESENT PORE BODIES AND PORE THROATS, RESPECTIVELY. WE SEEK A SPATIAL REARRANGEMENT OF PORE THROATS THAT MINIMIZES THE DIFFERENCE BETWEEN THE SEMIVARIOGRAM OF THE NETWORK AND A GIVEN MODEL SEMIVARIOGRAM. THE SPATIAL CORRELATION OF THE INITIALLY UNCORRELATED NETWORK INCREASES BY MEANS OF MC MOVES WHERE THE DIAMETERS OF A PAIR OF RANDOMLY CHOSEN PORES ARE INTERCHANGED. THE ALGORITHM PRESERVES THE INITIAL PORE SIZE DISTRIBUTION. FINALLY, THE CORRELATED PORE THROAT NETWORKS ARE USED TO DERIVE CORRELATED PORE BODY NETWORKS ONCE A GIVEN BODY-TO-THROAT SIZE RATIO IS SET. A SIMPLE PARALLEL IMPLEMENTATION OF THE ALGORITHM IS PRESENTED.
