| 摘 要： | 采用“两步法”制备了两种用于直接吸收式太阳能集热器的纳米流体循环工质.对这两种纳米流体及其基液进行闷晒实验,通过研究其闷晒温度随环境温度的变化情况来判断纳米流体光热转换性能的优劣.结果表明:铝纳米流体升温速率较基液和碳纳米管纳米流体快,闷晒温度高出基液近25℃,高出碳纳米管纳米流体近10℃,显示出很好的光热转换性能.

| Abstract: | Two kinds of Nanofluids,used as recycle fluids for collectors with direct absorption of solar energy,were prepared by the two-step method.The photothermal conversion properties of the two kinds of nanofluids and their base fluids were studied,the temperature changing with the environmental temperature through the insolation experiment.The results show that Al-nanofluids have higher rise velocity and insolation temperature than the base fluids and Carbon Nanotube Nanofluids,and that when the insolation tempe... |
