Generating Validated 3D Models of Microporous Ceramics


  • The authors would like to thank A. Mattern and C. Engel, Robert Bosch GmbH, for providing experimental data for the porous ceramics, and the MAVI group at Fraunhofer Institute for Industrial Mathematics, Kaiserslautern, for assistance with respect to image processing. The work on hand was co-financed by Bosch and the German Federal Ministry of Education and Research in the framework of the CorTRePa project with support code 03X3502C.12


Methods of generating and validating 3D models of microporous ceramics and computing the porosity and permeability by means of these models are presented. For five cordierite ceramic variants from the application area of diesel particulate filters, generated structure models with computed porosities and permeabilities are depicted. The generated pore structures are compared to the real structures by the chord length distribution. Furthermore, the computed porosities and permeabilities are compared to measurements.
