Original abstract
Advanced nanoparticles-based systems can improve the heat transfer of the base fluids. Here, a Computational Fluid Dynamics approach is implemented to study the impact of hybrid nanofluid utilisation on the thermal performance of a parabolic trough solar collector (PTSC) with an internal axial helical fin. Our numerical results revealed that as hybrid nanoparticles of SWCNT and Cu were added into Therminol ® VP-1 as the base fluid, the thermal performance of the PTSC was improved. Indeed, the combination of axial twisted fin with hybrid nanoparticles with enhanced heat transfer properties increased the thermal mixing of the fluid. As an example, at Re = 4000, increasing the volume fractions of Cu and SWCNT nanoparticles from 0.01 to 0.02 resulted in a 0.74% enhancement in the thermal efficiency of the PTSC.
