viscosity of water/oil mixtures
viscosity of water/oil mixtures
(OP)
Hi Everyone,
I need some help about undestanding why a mixture of 0.70 mass fracion of water, 0.30 of oil (c7-c30), has a viscosity of 3.4cP at 25psig and 180ºF, while pure water at the same conditions has a viscosity of 0.30cP and pure oil 0.91cP.
Thank u all for ur help.
Regards.

Additionally, I would like to know how to explain this behaviour in terms of interphase energy models.
I found in an article that the maximun viscosity value for this kind of emulsion is when the emulsion turns from o/w to w/o, what is the specific explanation for this behavior?
Thank U.

How can I predict the behavior of the viscosity of oil/water emulsions?
What correlation Can I select to calculate these viscosities?
Any one knows, How does Hysys make this calculations?
Thank u

thread135-120558: Viscosity of crude-water emulsion? seems to shed some light on the subject.

Fromm Googleing around I found that the bimonthly Jourmal of Rheology brings an article that could probably be found in a technical library or purchased titled Novel viscosity equations for emulsions of two immiscible liquids appearing in the J. Rheol. Volume 45, Issue 2, pp. 509-520 (March 2001)
