Influence of subphase viscosity on Langmuir monolayer flow

Description

The flow of a Langmuir monolayer driven through a floating channel by a surface pressure gradient is measured as a function of the channel width at different surface pressures. The comparison of the experimental data with the mathematical models shows that at low surface pressure the now is governed by the subphase viscosity, while at higher surface pressure the now is governed by both surface viscosity and bulk viscosity.
