Résumé

A numerical solution for the simulation of chemical vapor infiltration (CVI) of ceramic matrix composites is presented. This computational model requires a 3D representation of the preform. Gas transport and chemical reaction are simulated by a Monte Carlo random walk technique. The developed algorithm can also be used for the determination of effective transport and reaction properties in a porous medium. It is firstly validated by considering the simple case of diffusion and reaction in a flat pore. Results of infiltration of an actual fiber arrangement are described and discussed. Extension to deposition on a thin substrate with asperities is also studied.
