... computational cells, creating an interface region with finite thickness. A new numerical treatment is developed to determine the surfactant transport and adsorption/desorption in the interface region. From the variation of the surfactant interfacial concentration, the spatio-temporal variation in interfacial...

The study finds that the empirical model allows for computational results that agree very well with experiments also conducted in that study. The hindrance factors are characterized by the ratio of the ionic...
