Abstract
In the present studies the quantitative relationships between the structure and
flow properties of porous materials are addressed. In order to investigate such
relationships a series of foam structures with different porosity were
characterized by computer tomography. Later, 3D image analysis was applied to
obtain quantitative parameters of foam structures.
In order to calculate properties of the flow through porous structures, 3D
images obtained by computer tomography were numerically processed and
transformed into a finite element mesh. Simulation of fluid flow was performed
using a Finite Volume Method. Both qualitative characterization and numerical
simulation results, when compared, enabled us to establish structure-flow
relationships.
The preliminary results show that the pressure drop is strongly related to the
porosity of foams. The significant effect on flow properties exhibits also the
diversity of pore sizes.
The results will be discussed with respect to foam structure optimization for
several applications.
Keywords: ceramic foams, pressure drop, finite volume method.
