摘要(Abstract)：

采用聚乙烯吡咯烷酮作为表面活性剂，制备悬浮稳定的水基二氧化硅纳米流体，对水基二氧化硅纳米流体在圆管内的湍流流动和传热性能进行试验研究。结果表明：水基二氧化硅纳米流体的强化传热综合性能随着聚乙烯吡咯烷酮与二氧化硅质量比的增大呈现先增大后减小的变化趋势，聚乙烯吡咯烷酮与二氧化硅的质量比为1∶1的流体的强化传热综合性能最好；固定聚乙烯吡咯烷酮与二氧化硅的质量比为1∶1,水基二氧化硅纳米流体的强化传热综合性能随着二氧化硅纳米颗粒添加量的增加而增强，与纯水相比，二氧化硅纳米颗粒质量分数为6.0%的水基二氧化硅纳米流体的强化传热综合评价因子提高约46%,流动传热综合性能显著改善。
