Drainage rate of foams including three stages was investigated.

The drainage of AFFF (3%) has obvious effect on apparent viscosity before 600 s.

A Herschel–Bulkley modified model was built, which was relating to time and foam index.

Foam index of the modified model is decided by surfactant types and concentration.
