Water and Al 2 O 3 nanoparticle drops of different particle concentrations on heater surfaces boiled in corresponding nanoparticle concentration nanofluid [44]. (a) θ = 90°, water on clean heater wire; (b) θ = 46.5°, droplet of 0.00257 g/l concentration of Al2O3 nanofluid (APS 46 nm) on heater wire coated with nanoparticles after boiling this fluid; (c) θ = 33°, droplet of 0.00646 g/l concentration of Al2O3 nanofluid (APS 46 nm) on heater wire coated with nanoparticles after boiling this fluid.
