Abstract

Experiments were carried out to investigate the effect of surfactants on the boiling heat transfer coefficient of hybrid water-based nanofluids. In the present work, both Al₂O₃-SiO₂ and Al₂O₃-TiO₂ hybrid nanofluids were prepared with a 75:25 composition ratio and concentration of 0.01 v/v%, mixed with SDS surfactant of 40 ppm and prepared using ultrasonic process. It was found that Al₂O₃-SiO₂ and Al₂O₃-TiO₂ hybrid nanofluid enhance BHTC performance compared with distilled water, however, its performance will deteriorate gradually after 5 minutes of the experiment. Additional SDS in both Al₂O₃-SiO₂-SDS/Water and Al₂O₃-TiO₂-SDS/Water hybrid nanofluid will increase its BHTC performances up to 112.27% and 127.03% respectively compared with distilled water. Al₂O₃-SDS has better BHTC performance compared with Al₂O₃-SiO₂ and Al₂O₃-TiO₂ hybrid nanofluid which is 327.15% compared with distilled water.
