文摘

Experimental research on the heat transfer coefficient and friction factor of BioGlycol/water based TiO2 nanofluids. Turbulent flow in flat tube with 0.5–2 vol.% and operating temperatures of 30, 50 and 70 °C. The Nusselt number of nanofluids was approximately 28.2% greater than that of base fluid. New correlations for Nusselt number and friction factor with maximum deviation of 10% and 3% respectively.
