- •
Water based nanofluids of CNTs doped with Fe2O3 nanoparticles at different weight loading and concentration are considered.
- •
The thermal performance of shell and tube heat exchanger is investigated.
- •
The effects of volume concentration and Reynolds number on physical and thermal properties, enhancement of heat transfer, and pressure drop of nanofluids are evaluated.
- •
0.1 wt.% concentration of CNTs doped with 10 wt.% of Fe2O3 nanoparticles exhibits the best heat transfer performance.
- •
The nanofluids at different flow regimes have minor effects on the pressure drop.
