Abstract In this research work, MXene with a chemical formula of Ti3C2 is synthesized using wet chemistry method and suspended in pure olein palm oil (OPO) to formulate a new class of heat transfer fluid to investigate its thermal and energy performance in a hybrid PV/T solar thermal system numerically using COMSOL Multiphysics. In addition to this research work, Al2O3-water based nanofluid is compared with MXene-OPO nanofluid in the hybrid PV/T solar thermal system. The MXene-OPO nanofluid is prepared with a loading concentration of 0.01, 0.03, 0.05, 0.08, 0.1, and 0.2 wt %. MXene-OPO nanofluid with 0.2 wt % loading concentration exhibit 68.5% higher thermal conductivity than the pure OPO at 25 °C. The highest viscosity reduction is found by 61% when the temperature is raised from 25 °C to 50 °C for nanofluid with 0.2 wt % of MXene. Compared to PVT with Al2O3-water based nanofluid, MXene based nanofluid display about 16% higher thermal efficiency improvement at 0.07 kg/s flow rate. About 9% heat transfer coefficient improvement is found for the PVT with MXene nanofluids compared to PVT with Al2O3-water heat transfer fluid. MXene nanofluid may reduce PV temperature by 40% compared to stand alone PV module.

油精棕榈油与MXene作为新型传热流体改善混合PV/T系统的热能性能

摘要 在本研究工作中，采用湿化学法合成化学式为 Ti3C2 的 MXene，并将其悬浮在纯棕榈油 (OPO) 中以配制新型传热流体，以研究其在混合 PV/使用 COMSOL Multiphysics 对 T 太阳能热系统进行数值计算。除了这项研究工作，Al2O3 水基纳米流体与混合 PV/T 太阳能热系统中的 MXene-OPO 纳米流体进行了比较。MXene-OPO 纳米流体的制备负载浓度为 0.01、0.03、0.05、0.08、0.1 和 0.2 wt%。MXene-OPO 纳米流体在 25°C 时的热导率比纯 OPO 高 68.5%，负载浓度为 0.2 wt%。对于含有 0.2 wt% MXene 的纳米流体，当温度从 25 °C 升高到 50 °C 时，发现最高的粘度降低了 61%。与采用 Al2O3 水基纳米流体的 PVT 相比，MXene 基纳米流体在 0.07 kg/s 流速下的热效率提高了约 16%。与使用 Al2O3-水传热流体的 PVT 相比，使用 MXene 纳米流体的 PVT 的传热系数提高了约 9%。与独立的光伏组件相比，MXene 纳米流体可以将光伏温度降低 40%。
