Ift interfacial tension
WebIn terms of interfacial tension (IFT), dynes/cm and mN/m are the common units. Both units are the same. Measurement of the tension between immiscible liquids is used in numerous industrial applications. Get subject wise printable pdf … Web15 dec. 2024 · The basic idea is that you set up a slab of the liquid in a simulation box with the direction normal to the surfaces elongated, from which you can compute the surface tension from the difference between the pressure tensor components normal and parallel to the interface.
