文摘
- •
The viscosity of a two-dimensional foam depends intimately on its structure.
- •
The viscosity of a monodisperse foam oscillates as bubbles slide past each other.
- •
The viscosity of a bidisperse foam declines in time as bubbles size-segregate.
- •
We propose a mixing rule for the viscosity of bidisperse foams.
