/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.
