Parabolic trough collectors (PTCs) are essential for solar thermal energy systems, and their efficiency can be significantly enhanced using turbulators nanofluids. This numerical study introduces three novel fin-spiral turbulator configurations (4, 7, 10 blades) to enhance heat transfer within the absorber tube. Additionally, nanofluid types including water-based single-walled carbon nanotubes (SWCNT), cupric oxide (CuO), a hybrid SWCNT-CuO, at concentrations of 1%, 3%, 5% were evaluated. The simulations, conducted in ANSYS-FLUENT under steady-state turbulent flow conditions, revealed that 10-blade improved coefficient by 12.25% compared plain tube, while SWCNT-CuO/water exhibited 24.8% increase conductivity base fluid. Furthermore, maximum pressure drop 44% was observed volume concentration Reynolds number 12,500. also demonstrated Performance Evaluation Criterion (PEC) 15.6% CuO/water nanofluid. These findings highlight effectiveness combining nanofluids optimize hydraulic performance PTC systems.
