Voronoi Tessellations Description of Cast Composite Solidification Processes.

The paper presents a method to analyse the thermal processes occurring in the cast composite solidification. The domain of cast is formed by parallel fibres bundle randomly immersed in a host metal matrix. The heat is transferred from the metal matrix and absorbed by fibres. The objective of this paper is to evaluate the volumetric fraction of fibres for which the solidification of metal matrix occurs. Our method is to compute Voronoi diagrams with Voronoi regions representing the geometry location of the fibres in the metal matrix and to use these regions as control volume within a variant of Control Volume Method.
