Gas-liquid foams are important in applications ranging from oil recovery and mineral
flotation to food science and microfluidics. Beyond their practical use, they represent an …

Liquid foams are an extreme case of multiphase flow systems: capable of flow despite a very
high dispersed phase volume fraction, yet exhibiting many characteristics of not only …

Foams are common, complex, and not well understood. Most of the common foams are a
two-phase medium of gas and liquid with a particular structure consisting of gas pockets …

We formulate a large-scale network model for the dynamics and stability of a planar (gas–
liquid) foam with low liquid fraction composed of approximately polygonal gas bubbles. We …

In this work, we present direct observation of foam flow through a 2D porous microfluidic
device. Through a specially designed image processing workflow, we perform individual …

The story of some recent developments in foam rheology is related at key points to the
remarkable early contributions of Henry Princen, who pioneered the rigorous modern …

Foam evokes many different images: waves breaking at the seashore, the head on a pint of
Guinness, an elegant dessert, shaving, the comfortable cushion on which you may be …

Modeling the physics of foams and foamlike materials, such as soapy froths, fire retardants,
and lightweight crash-absorbent structures, presents challenges, because of the vastly …

Foams are ubiquitous in our daily lives. Their presence is highly desirable in certain foods,
drinks and cosmetics, and they are essential in oil recovery and mineral extraction. In some …

The origin of the dissipation in liquid foams is not fully understood, especially in the large
deformation, large velocity regime. Numerical simulations, now very accurate in the quasi …
