Heat transfer coefficient of nucleate boiling in low concentration level of single and hybrid Al2O3-SiO2 water-based nanofluids

Experiments were conducted to identify the Heat Transfer Coefficient (HTC) in saturated pool boiling of single and hybrid water-based nanofluids. In these experiments, Al2O3 and SiO2 nanoparticles were selected and diluted into two separate single nanofluids, and they were mixed in a different ratio...
