摘要

基于计算流体动力学中的有限体积法，研究了Al

/Syltherm800导热油纳米流体作为传热介质时槽式太阳能热发电集热器的性能，建立了真空管集热器的三维模型，进行了光学模拟和传热数值模拟，并通过实验进行了验证。在非均匀热流密度分布的情况下，研究了进口温度、进口流速等运行参数对采用纳米流体的槽式集热器传热性能的影响规律。结果表明：随着Al

体积分数的增加，槽式集热器的换热性能及热效率均有所提高；进口温度、进口流速等运行参数对集热器的传热性能影响很大，随着进口温度的上升和进口流速的减小，纳米流体对传热性能的影响程度逐渐增大。

Abstract

Based on the finite volume method in computational fluid dynamics

the performance of the trough solar thermal power collector with Al

/Syltherm800 oil nanofluid as heat transfer fluid was studied. A three-dimension model of the vacuum collector was established

optical simulation and heat transfer numerical simulation were carried out and verified by experiments. Under the condition of non-uniform heat flux distribution

the influence of inlet temperature and inlet velocity on the heat transfer performance of the trough collector with nanofluid was studied. The simulation results show that the heat transfer performance and heat efficiency of the trough collector are improved with the increase of Al

volume fraction. The heat transfer performance of the collector is greatly influenced by the inlet temperature and the inlet velocity. With the increase of inlet temperature and the decrease o

f inlet velocity

the influence of the nanofluid on the heat transfer performance increases gradually.
