摘要:
直接吸收式太阳能集热器是一种经济有效的吸收太阳能的方法.提出了利用流速控制纳米棒流体从而增强其光谱吸收的方案,并对纳米流体实际光学特性进行实验研究.分析了光照强度、流速以及浓度对纳米棒流体光热特性的影响.纳米流体出口温度随光照强度增大而提升,当流速为0.5 mL/min,辐射强度为600 W/m2时,纳米流体出口温度相较400 W/m2的照射下提升18.5%.纳米流体的光学性能在很大程度上取决于其浓度.加入金纳米棒颗粒明显提高了去离子水的吸热性能.0.3 ppm的金纳米棒流体在0.75 mL/min流速控制时,接受800 W/m2的照射,光热转换效率可以达到52.3%,相较无流速控制的效率提升162%.在直接吸收式太阳能集热器中添加纳米棒状颗粒,并进行流速调控,可有效提升集热器集热性能.
Abstract:
Direct absorption solar collector is an economical and effective way to absorb solar energy. In this paper, a scheme of controlling the flow rate of nanorod fluid to enhance its spectral absorption is proposed, and the actual optical properties of nanorod fluids are experimentally studied. The effects of illumination intensity, flow rate and fluid concentration on the photothermal characteristics of nanorod fluid are analyzed. The outlet temperature of the nanofluid increases with the increase of illumination intensity, especially for the 0.5 mL/min flow rate control, 600 W/m2 irradiation, the outlet temperature of the nanofluid is increased by 18.5% compared with that under 400 W/m2 irradiation. The optical properties of nanofluids depend largely on the concentration. The addition of gold nanorods can significantly improve the heat absorption performance of deionized water. When the flow rate of 0.3 ppm gold nanorods is controlled at 0.75 mL/min, the photothermal conversion efficiency reaches to 52.3%, which is 162% higher than that without flow rate control. It is of great significance to add nanometer rod-shaped particles into direct absorption solar collector and control them by flow rate.
