Investigation of Water Separation from Water-in-Oil Emulsion Using Centrifugal Field and Gravity with CFD Method

Abstract:

Numerical simulation has been carried out to investigate water separation from emulsion with new equipment designed by ourselves. Three rotate speed of 300r/min,1500r/min,3000r/min have been calculated using Reynolds stress model ,which is at the same water volume fraction, droplet diameter and other physical parameters .When the rotate speed increase, the velocity and pressure drop of fluid tends to increase. Due to the effect of centrifugal field, the water volume fraction of near the wall is larger than that of inner fluid. Because of the gravity, the water volume fraction of bottom is larger than that of upper.
