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.
