Abstract  

High performance nanofluids were produced by a microfluidizer, and a spectrophotometer basing the integral ball principle was used to measure the transmissivity of SiO2 nanofluids in total solar irradiance band with various particle sizes, volume fraction and optical path. By analyzing the experimental results, it was observed that the physical characteristics of nanofluids such as particle sizes, volume fraction and optical path would affect the transmissivity of SiO2 nanofluids. The measurement of the transmissivity of SiO2 nanofluids with different optical path was realized by using different thick sample pools. The results indicated that the transmissivity variation of the 7 nm SiO2 nanofluids with the different optical paths obeyed the LabbertBeer law, however, not happened when the diameter was 40 nm for particle dispersion.

SiO2纳米流体透射率影响因素实验研究

利用高压微射流法制备了多种SiO2纳米流体,并用分光光度计结合积分球原理测试了不同粒径、不同体积分数及不同光程下SiO2纳米流体在太阳能辐射全波段的透射率.比较实验结果发现,SiO2纳米流体的颗粒粒径,以及其体积分数的不同对纳米流体的透射率有不同程度的影响.通过定制不同厚度的样品池,测试不同光程下SiO2纳米流体的透射率.实验发现:7 nm SiO2纳米流体的透射率随光程的变化仍符合朗伯比尔定律,而40 nm SiO2纳米流体由于颗粒散射加剧导致结果偏离朗伯比尔定律.
