  • Pool boiling heat transfer characteristics of TiO2-water nanofluids on laser-textured copper surfaces
    Hadžić, Armin ; Može, Matic ; Golobič, Iztok
    Boiling is an essential process for many industrial applications, such as refrigeration, distillation and chemical processes. This study presents experimental investigation of pool boiling heat ... transfer enhancement by using TiO2-water nanofluid in combination with laser-textured copper surfaces. Nanofluids with two different mass concentrations of nanoparticles (0.001 wt.% and 0.1 wt.%) were prepared using sonification and degassed distilled water. Boiling experiments on laser-textured copper surfaces were performed using the nanofluids at atmospheric pressure. The results demonstrate that the heat transfer coefficient using nanofluids is deteriorated compared to pure water on the reference and laser-textured surface, while the critical heat flux is significantly improved at 0.1 wt.% nanoparticle concentration.
