摘    要:为了得到简单易行的定量反映纳米流体颗粒团聚的方法,在分析纳米颗粒团聚与纳米流体透射比之间关系的基础上,提出团聚体平均颗粒数这一可以定量反映纳米流体内颗粒团聚状况的参数,并推导出基于纳米透射比的团聚体平均颗粒数的计算式.所提出公式的计算结果与利用反映实验数据的三维DLCA模型得到的团聚体平均颗粒数吻合较好,反映了该计算式的有效性.

关 键 词:纳米流体  颗粒团聚  透射比  定量检测方法

Abstract:In order to get a simple and low-cost method to reflect the nanoparticles aggregation quantitatively,the relationship between nanoparticles' aggregation and nanofluids' transmittance was analyzed and the mean particles number of nanoclusters was proposed as a parameter to reflect the nanoparticles aggregation quantitatively.The calculation equation of the mean particles number of nanoclusters based on nanofluids' transmittance was derived.The calculated mean particle numbers of nanoclusters by the equation were compared with the results gotten from the three dimensional DLCA model based on the experimental data.These two kinds of results are similar and the feasibility of the calculation equation is verified.
Keywords:nanofluids  particles aggregation  transmittance  quantitative test method
