文章摘要
Three-dimensional simulation of a multiphase flow is performed using the Eulerian-
Eulerian finite volume method in order to evaluate the separation efficiency and velocity field of deoiling
hydrocyclones. The solution is developed using a mass conservation-based algorithm (MCBA) with
collocated grid arrangement. The mixture approach of the Reynolds stress model is also employed in
order to capture features of turbulent multiphase swirling flow. The velocity field and separation efficiency
of two different configurations of deoiling hydrocyclones are compared with available experimental
data. The comparison shows that the separation efficiency can be predicted with high accuracy using
computational fluid dynamics. The velocity fields are also in good agreement with available experimental
velocity measurements. Special attention is drawn to swirl intensity in deoiling hydrocyclones and it is
shown that the differences in velocity and volume fraction fields of different configurations are related to
swirl distribution.
