"Prediction and evaluation of energy and exergy efficiencies of a nanof" by Yuanlei Si, Frantisek Brumercik et al.
The Photovoltaic thermal (PVT) collector performance is numerically investigated considering the effect of using needle fins in the serpentine channel with Nanofluid (NF). The influence of increasing the nanoparticle concentration (φ) and Reynolds number (Re) on the energy and exergy features of the PVT device is examined. A comparison is made between the hydrothermal characteristics of the PVT with the finned and plain serpentine channels. The utilization of needle fins improves the thermal efficiency (ηth), electrical efficiency (ηel), and overall efficiency (ηel) by 8.56–10.22%, 0.13â...
