integral foam molding of light metals technology foam physics and foam simulation
p the development of cost effective techniques to produce metal parts with integrated cellular structure is the newly developed process of integral foam molding . br this book shows in three parts the technology the fundamentals and the simulation models for the integral foam molding of light metals . part i technology shows for the first time that foaming of metals is possible by applying molding techniques very similar to polymer integral foam molding . it introduces and discusses in detail a low pressure and a high pressure process of foam molding . part ii physics is devoted to the physics of foaming with special emphasis on the very short time scale which is characteristic for integral foam molding . although very complex in detail foam formation is shown to underlie simple evolution laws determined by the way how foam stabilization is realized . br part iii numerical simulation presents a new lattice boltzmann approach for the treatment of free surfaces is developed and applied on foam evolution problems . for the first time the numerical simulation of foam evolution starting from nucleation until decay is accessible . the interplay between hydrodynamics capillary forces gravity and bubble coalescence processes leads to complex phenomena such as topological rearrangements avalanches drainage etc. without further model assumptions .
