Figure  1.  3D  renderings  of  µ-CT  scans  of  a  partly  infiltrated  C/C  sample  shaped for CT acquisition at 2 distinct resolutions
Figure  2.  Comparative  sketch  of  the  two  random-walk  algorithms.  a)  Gas- Gas-kinetic random walk interacting with pore walls; b) Brownian motion in a  het-erogeneous, anisotropic continuum
Figure  3.  a)  Rendering  of  a  simulated  matrix  with  parameters  Kn  =  0.035  and P c  = 0.16
Figure  4a  displays  an  example  infiltration  with  a  low  initial  value  of  the  global Thiele modulus ( Φ 0  = 0.05)
