Simulations Reveal Morphological Transition In Simple Foams

Summary:
By deriving an equation of state for compressible foam, and then simulating it numerically, University of Illinois researchers predict a dramatic morphological change that will occur as the surface tension is increased or, equivalently, the volume of the foam is greatly expanded. Foams are ubiquitous in nature and widely used in industry, from foamy foods such as bread and ice cream to foamy materials such as plant stems, bones, magma and foam rubber.

CHAMPAIGN, Ill. -- By deriving an equation of state for compressible foam, and then simulating it numerically, University of Illinois researchers predict a dramatic morphological change that will occur as the surface tension is increased or, equivalently, the volume of the foam is greatly expanded. Foams are ubiquitous in nature and widely used in industry, from foamy foods such as bread and ice cream to foamy materials such as plant stems, bones, magma and foam rubber. All foams have one characteristic in common: the bubble-delimiting films minimize surface energy by encapsulating the largest volume using the least amount of material.
