The viscosity of a foam (air in water emulsion)

The apparent viscosity (η) of a foam (air in water emulsion) at various shear rates ( D) (from 0 to 300 s −1) was found to increase exponentially with the increase of the inner-phase volume fraction (φ), η = η 0e Kφ . η 0 is the viscosity of the continuous phase of the foam. K was found to be a func...

Description
Summary:The apparent viscosity (η) of a foam (air in water emulsion) at various shear rates ( D) (from 0 to 300 s −1) was found to increase exponentially with the increase of the inner-phase volume fraction (φ), η = η 0e Kφ . η 0 is the viscosity of the continuous phase of the foam. K was found to be a function of the shear rate.
