Flow boiling heat transfer enhancement on copper surface using Fe doped Al2O3-TiO2 composite coatings

- Fe-Al2O3-TiO2 composite coatings were coated on the copper using spray pyrolysis.
- Effect of Fe doping on porosity was determined using AFM.
- Effect of Fe doping on hydrophilicity was determined.
- Higher enhancement in CHF was obtained for 7.2 at% Fe doped coated sample.
