Abstract

A foam, which has gas bubbles crowding themselves in a liquid, will coarsen by the rupture of liquid bridges causing the coalescence of adjacent bubbles. In metallic foam, such coarsening is rapid. The aim is to devise a protocol for freezing metallic foam into a strong, lightweight metal bar before the bubbles have combined. Local analysis based on long-wave approximations is used to study the fluid flow and heat transfer in individual lamellae as well as their stability. We discuss how these local analyses can be used as the building blocks for a network model of foam which will allow us to investigate coarsening and freezing at a macroscopic level across multiple lamella branches.
