Abstract:

Nanofluids have become a research focus in the field of solar thermal applications due to their excellent photothermal conversion performance. In this paper, a two-step method was used to prepare water-based carbon black nanofluids with mass fractions in the range of 0.001%—0.02%, and their stability was characterized. The photothermal conversion performance of water-based carbon black nanofluids with different mass fractions was tested under simulated sunlight and natural light irradiation. It was found that within a certain range, with the increase of carbon black mass fraction, the photothermal conversion efficiency of the nanofluid was significantly improved. The photothermal conversion efficiency of 0.009% nanofluid under natural light can reach 60.31%, reflecting excellent photothermal conversion performance. This study confirmed that water-based carbon black nanofluid was an excellent solar photothermal conversion medium, which can achieve efficient solar photothermal conversion.

Key words: nanofluid, carbon black, solar energy, photothermal conversion

摘要:

纳米流体由于其优异的光热转换性能,已成为太阳能热应用领域的研究重点。采用两步法制备了质量分数在0.001%~0.02%范围内的水基炭黑纳米流体,并对其稳定性进行了表征。在模拟太阳光和自然光照射下对不同质量分数的纳米流体进行光热转换性能测试,发现在一定范围内随着炭黑质量分数的增加,纳米流体光热转换效率显著提高,0.009%的纳米流体在自然光照射下光热转换效率可以达到60.31%,体现出优异的光热转换性能。本研究证实了水基炭黑纳米流体是一种优异的太阳能光热转换介质,可以实现太阳能光热高效转换。
