A Comparative Study of Magnetized Nanofluids Cuo and AIO203 in an Integrated Solar Photovoltaic-Thermal, Heat Pipe and Heat Pump Hybrid System

A comparative study is presented here and applied to a “hybrid system to enhance the thermal energy efficiency and reduce carbon footprint, which is composed of photovoltaic-thermal solar panels, heat pipe, and heat pump, is presented hereby”. A “two-dimensional heat transfer and fluid flow dynamic model was developed and presented using CUO and AiO203 to describe the behavior of the different components of the hybrid system under different solar irradiance conditions, AiO203 Nanofluid, and different refrigerants”. The model is based on “dynamic mass and energy equations coupled with the heat transfer formulas, and thermodynamic properties of nanofluid, and refrigerants mixtures. Finally, the presented model has been validated, and its prediction is fairly compared with available data.” It confirmed that CUO performs superior to AiO203 and other nanofluids reported in the literature.
