EXPERIMENTAL STUDY OF POOL BOILING OF NANO-FLUIDS

Pool boiling of Nano Al2O3, TiO2, and ZrO2 of concentrations 0.1, 0.4, 1.0, 2.5, 5.0 g/L in distilled water (which is taken as a base fluid) were experimentally studied in a test boiling chamber of stainless steel cylindrical vessel of 15 cm diameter and 30 cm length, provided with a 500 W heater. Results showed that the Nano-fluid heat transfer coefficients are higher than that for distilled water. The increments of heat transfer coefficient of Al2O3-H2O Nano-fluid was more than that for TiO2-H2O Nano- fluid which is more than that for ZrO2-H2O Nano fluid. The increment beyond 1 g/L were slight for nanomaterials used.
