Simulation of the Foaming Process

摘要

The Kerroc glass foams can be made with different porosities, depending on two thermodynamics parameters of the foaming process, temeprature and duration of the expansion stage. Notably, at lower temperatures, one can pass fromtotal imperviousness to permeability as the time of expansion increase. The increase in bubble connectivity with time is simulated, through a generalisation of Voronoi tessellation,s by the build-up of a network of physical contacts between bubbles which ultimately percolates. The temperature is modelled by different distributions of spheres, representing a snapshot of the foam at different temperatures during its expansion.
