We are studying interfacial tension (IFT) in oil-water-polymer-surfactant systems using DPD.
One would expect the increase in simulation box size to yield better results. However, we are noticing that the interfacial tension values are almost constant with box size up to a point, after which a sharp drop in value of IFT occurs.
We are not sure what is going wrong here, any explanation will be appreciated.
Hello Dear Professor
In you study, you varied the polymeric surafcatant concentration?
I suggest to you to variny the amount of surfactant by increasing and decreasing it, especially after the critical point. so we can have more data, for better inderstanding of the fenomenon!
Dear Ali Al-Matar ,
How can we relate the stress aoutocorellation function to interfacial tension? can you explain please?
