摘　　要：航空煤油在使用过程中,要求洁净度高、无机械杂质等有害物质。探讨了旋流器用于煤油-杂质二相分离情况,对煤油-杂质在液-固旋流器内的分离过程进行了数值模拟,并研究了杂质粒径、入口处理量对分离效率的影响。计算结果表明:旋流器底流口阀门在适当时间内开启和关闭,可以避免被分离出的杂质再次污染液体和防止液体的流失;当杂质粒径大于一定值时,才能被有效地分离;旋流器的处理量存在着较优区间。这些结果可为旋流器在实际工程应用中的操作提供指导。(图7,参15)Aviation kerosene requires high cleanness and no harmful substance like mechanical impurity in its usage. This paper discusses the case of using hydrocyclone in the two-phase separation of kerosene and impurity. Numerical simulation is used to simulate the separation process of kerosene and impurity in the liquid-solid hydrocyclone and the impact of impurity diameter and inlet throughput on separation efficiency. The calculation result shows that the re-pollution of kerosene by the separated impurity and loss of kerosene can be avoided if the valve at the downflow pipe of hydrocyclone opens and closes at proper time. The impurity can only be effectively separated when its diameter is above a certain value and there exists a better range in the throughput of hydrocyclone. These results can provide guidance for the operation of hydrocyclone in practical application. （7 Figures, t5 References）
