The purpose of this paper is to demonstrate a method for modeling of cellular structures by means of Voronoi tessellation and to conduct a validation by comparison with real metal foam structures.
Heat propagation behavior of open-pore metal foams is studied for both experimental as well as computer-modeled structures showing excellent agreement. The 3D open-pore structure of the real foam is reconstructed from 2D light microscope images in-depth.
An algorithm to create synthetic open-pore foam structures has been developed.
The algorithm for modeling synthetic open-pore cellular structures allows the random distribution of the individual pores close to reality.
