Interfacial Tension Sample Clauses

Interfacial Tension. The two models for calculating microemulsion/oil (σ23) and microemulsion/water (σ13) interfacial tension (IFT) are based on Xxxxx and Xxxx [1974] and Huh [1979]. The IFTs for water and oil (σow) and water and air (σaw) are assumed to be known constants. Xxxxx et al. The first IFT model is based on Xxxxxxxx'x modification (Xxxxxxxx, 1981) of the model of Xxxxx and Xxxx [1974]. Once the phase compositions have been determined, the interfacial tensions between microemulsion and the excess phases (σ13, σ23) are calculated as functions of solubilization parameters: ⎧log10 σℓ3 = log10 Fℓ + Gℓ2 + G ℓ1 for Rℓ3 ≥ 1 ⎨
