Performance of agitated serpentine heat exchanger using metallic nanofluids

- Nanofluid flow in the agitated serpentine heat exchanger is studied.
- Cu-water, Fe-water, and Ag-water nanofluids are applied as working fluid.
- Effects of flow rate, agitator speed, and tube diameter are examined.
- Performance improves by using nanofluids.
- Cu-water nanofluid shows a better thermal-hydraulic performance.
