The separation of oil, water, and sand has always been a significant problem in the treatment of oily sludge in oil field and petroleum refinery. The flow field and separation performance in a new three‐phase decanter centrifuge with vertical boards and annular liquid separation plate for oil‐water‐solids separation were investigated, using the computational fluid dynamics (CFD) software Fluent with Euler‐Euler three‐phase flow model, which provides a basis for the improvement and optimization of the centrifuge. After calculation, the velocity and pressure field were analyzed. The increase of solids content of the feed affected the separation efficiency regularly, and high or low treatment capacity also had a certain impact on the separation efficiency.

油水固分离三相Dec析离心机的设计及计算流体动力学分析
油，水和沙的分离一直是油田和炼油厂处理含油污泥的重大问题。使用计算流体力学（CFD）软件Fluent和Euler-Euler三相流，研究了新型带有垂直板和环形液体分离板的三相倾析器离心机用于油-水-固体分离的流场和分离性能模型，为离心机的改进和优化提供了基础。计算后，分析了速度和压力场。进料中固体含量的增加有规律地影响分离效率，处理能力的高低也对分离效率有一定影响。
