Results of the simulations for compressional (\(V_p\)) and shear (\(V_s\)) wave velocities as a function of pore aspect ratio for different samples and image orientations using two effective medium models, proposed by Kuster-Toksöz (top) and Self-Consistent (bottom), respectively. Each subplot shows the variation of wave velocities with aspect ratio for B4 radial (B4 rad), B4 axial (B4 ax), D1 radial middle (D1 rad middle), and D1 radial top (D1 rad top). Both models reflect increasing velocities with higher aspect ratios, highlighting differences in poroelastic response between samples and orientations.
