Resumen:
Simulations of bubble growth in porous media were carried out via a 2Dnumerical automaton built under
a set of hypotheses derived from experimental observations at pore scale. Various types of 2D numerical networks
(320 ?~ 320 sites and corresponding bonds) were used as models of porous media to study the consequences of
the spatial correlation length, ÌBB, existing among the porous network void entities with respect to the growth of
a gas cluster by solute diffusion occurring therein. The studied range was ÌBB ?¸ [0.86 ?} 0.12, 10.63 ?} 0.12], in
lattice units. The results obtained show that bubble development is truly affected by ÌBB. The growth law exponent?~ 320 sites and corresponding bonds) were used as models of porous media to study the consequences of
