Phase-Field simulation of surfactant adsorption onto flat and droplet interfaces
Surfactant adsorption plays a vital role in our daily life, it is also an integral part when it comes to the establishment of microfluidic devices, a developed Phase-field model based on free energy of two fluids with a surfactant is analyzed. The ill-posedness of the model and proposed alternative...
