Compared to a single-phase cooling system, which uses the sensible heat of the coolant, a pool boiling cooling system can achieve a greater heat transfer coefficient by capitalizing on the latent heat of vaporization of the coolant. Nanofluids are known to provide the added benefit of an increase in the heat transfer coefficient due to their high thermal conductivity. In order to simulate pool boiling with water-based nanofluids, a computational model is constructed using the volume of fluid (VOF) model in the FLUENT computational fluid dynamics code. The simulations are performed with saturated pure water and water-Al2O3 nanofluids using a two-dimensional computational domain with a width of 5 cm and a height of 20 cm. An isothermal condition is applied to a vertical surface with a heated length of 2 cm which is exposed to the working fluids, the surface temperature of which is 5 K, 10 K, 15 K and 20 K higher than the initial temperature of the working fluids. The numerical results are verified by comparing the experimental volume fraction data in the pool boiling. The fluid flow and heat transfer characteristics of pool boiling are examined for different wall superheats and nanoparticle concentrations.
