4. CONCLUSION
Comparisons with classic empirical or analytical models (Ergun, Carman-Kozeny,
Rumpf-Gupte, Du Plessis) have shown that the permeability K of a macroporous
bioceramic (or the dimensionless permeability K') can be directly and numerically
calculated from a computed model with enough accuracy from the Navier-Stoke's
equations and the Darcy's law. These comparisons have been performed for a steady
laminar regime flow of a physiological fluid which properties are similar to those of the
water.
These results will lead us to study the random packing spheres. It will aim the
determination of the distribution of the velocity and of the pressure in a macroporous
bioceramic through the simulation of the flow in it.
