Spray cooling is among the most popular liquid cooling strategies, given the high heat transfer coefficients that can be delivered [1]. However, increasingly demanding heat loads in applications such as electronics cooling have pushed researchers to further enhance the heat transfer processes, by altering the surfaces and/or the fluids e.g. [2-4]. Fluids with nanoparticles are pointed to have great potential to improve heat transfer processes, given their potentially higher thermal properties. However, increasing the concentration of the nanoparticles may alter significantly other physical properties such as the viscosity, which affect the fluid flow and may eventually reverse any advantage of adding the nanoparticles. Furthermore, while most authors have focused simply on the effect of the nanoparticles on the bulk properties of the fluid, studies on the wettability and on the interaction effects of the particles on the surfaces and on droplet-droplet interactions is scarcely reported. The actual effects of adding nanoparticles in the fluid flow characteristics and, particularly in the mechanisms of atomization, have also been drawn to a secondary plane.
