Area of Science:

  • Materials Science
  • Renewable Energy Engineering

Background:

  • Photovoltaic thermal (PVT) systems require efficient cooling, especially in extreme environments like Baghdad's summer.
  • Nanofluids offer enhanced thermal properties compared to traditional coolants.
  • Multiwalled carbon nanotubes (MWCNTs) are promising nanoparticles for improving heat transfer in nanofluids.

Purpose of the Study:

  • To determine the optimal nanofluid composition for cooling PVT systems in Baghdad's hot climate.
  • To evaluate the impact of base fluid, surfactant, and sonication time on nanofluid performance.
  • To assess the thermal conductivity, stability, and overall efficiency of MWCNT-based nanofluids in PVT systems.

Main Methods:

  • Investigated water as the base fluid, comparing it with ethylene glycol (EG), propylene glycol (PG), and heat transfer oil (HTO).
  • Examined the role of surfactant (CTAB) and sonication time in preparing the MWCNT nanofluid.
  • Tested the optimized nanofluid in a PVT system under Baghdad's environmental conditions.

Main Results:

  • The optimal nanofluid (0.5% MWCNTs, water, CTAB, 3.25 hours sonication) showed significant thermal conductivity enhancements: 119.5% over EG, 308% over PG, and 210% over HTO.
  • The nanofluid-cooled PVT system achieved 88.85% higher electrical efficiency than standalone PV and 44% higher than water-cooled PVT.
  • Thermal efficiency increased by 20% compared to water-cooled PVT systems, with maintained performance at peak temperatures.

Conclusions:

  • MWCNT-based nanofluids, particularly with water and CTAB, are highly effective for PVT cooling in extreme heat.
  • Optimized nanofluids significantly enhance both electrical and thermal efficiencies of PVT systems.
  • This approach offers a viable solution for improving PVT performance in challenging climates.
