Flow boiling heat transfer coefficient of DI water and nanofluids inside microscale channels under conditions near the critical heat flux (CHF)

This study concerns an experimental evaluation of the heat transfer coefficient for saturated flow boiling of DI water and nanofluids under conditions close to the critical heat flux. Experimental data were gathered for DI-water-based nanofluids (composed of Al2O3 40–80 nm, Al2O3 10 nm, and SiO2 80 nm in volumetric concentrations up to 0.1%) and pure DI water in microscale channels (1.1 mm internal diameter) as received from the manufacturer and...
