Ye, X.-H., Wang, J.-F., and Shi, W.-D., 2019. Liquid-solid two-phase purification performance of ship electrostatic oil purifier. In: Gong, D.; Zhu, H., and Liu, R.

This paper aims to disclose the oil purification features of electrostatic oil purifier through micro-scale numerical simulation of the liquid-solid two-phase flow. For this purpose, the scalar potential field, Huilin-Gidaspow liquid-solid drag force and particle electrophoresis force model were integrated into the Euler-Euler model. Then, the integrated model was applied to numerically simulate the performance of electrostatic oil purifier. The simulation reveals that the solid phase removal effect of the filter element directly bears on the solid phase content in the electrostatic oil purifier; particle movement in the purifier can be intensified by increasing the electric field strength, particle diameter or solid phase volume fraction, while the rise of flow rate suppresses the removal of the solid phase; the dimensionless criteria equation, which is obtained through the dimensionless analysis of relevant quantities based on the Buckingham p theorem, can accurately depict the oil purification rate.
