Adsorption of surfactant at an interface change the interfacial boundary condition and affect mass and momentum transfer.
Hence, the modeling and understanding of drop motions with adsorption of surface-active agent is required for designing the industrial equipment.
Several researchers simulate the flows about bubbles/drops by using the Frumkin-Levich model or the Langmuir adsorption model.
Hosokawa et al. evaluated the surfactant concentration at the mobile interface and indicated that it couldn't be evaluated accurately by the Frumkin-Levich model.
On the other hand, the applicability of these adsorption models to flows about deformation bubbles/drops isn't investigated.
In this study, we evaluate the applicability of these adsorption models to flows about deformation bubbles.
We confirmed that the boundary-fitted SFV can be applied to the deformation interface by using the arbitrary square measurement region.
