Experimental study of pool boiling of Nano-fluids

الملخص EN

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 Nanofluid which is more than that for ZrO2-H2O Nano fluid.

The increment beyond 1 g/L were slight for nanomaterials used.
