摘要
本文采用数值模拟的方法初步研究了颗粒聚集对纳米流体强化换热性能的影响。在流体中随机生成纳米颗粒团聚状态,并对其热性能进行数值模拟,结果表明,纳米颗粒的聚集将会导致流体换热性能的下降,降低程度与纳米颗粒体积分数以及聚集程度有关。
Numerical simulations have been conducted to investigate the effects of nanoparticle aggregation on the heat transfer enhancement of nanofluid. The aggregation status is generated randomly. The calculation results suggest that the nanoparticle aggregation acts to degrade the thermal performance of the nanofluid, and the degree of the degradation relates to the aggregation status and the volume fraction of the nanofluid.
