Abstract (technical / expert description):


Until today, metallic foams are not common despite their potential for energy absorption and ultra-light components. The main disadvantage are the inhomogenities of the pore structure, which includes variations in the pore size, geometry and wall size. The aim is to understand the underlying effects during foam formation to improve the process.



The implemented software bases on the lattice Boltzmann method, covers he most important physical effects during foam formation and is able to predict modified process strategies. The implementation comprises the hydrodynamic, diffusive and thermodynamic conservation equations applied on free surfaces. The physical models cover the growth, coarsening, reordering and collapse of foam bubbles as well as effects of the whole pore network like aging and drainage due to capillarity and wetting.
