Abstract
Experimental investigations were made on the vaporizing behavior of water droplet on heated brass surfaces with different polish finishes; rough polish #400 to extremely fine polish #15000 in comparison to previous studies. The surfaces were nickel & gold plated for good experimental reproducibility. Familiar lifetime curve with LFP was obtained in the case of intermediate polish, and the surfaces of rough polish required higher LFP, as was reported in previous studies. However, the droplet showed curious manner, bound with splashing fine droplets, and vaporized faster on the finely polished surface at surface temperatures just above LFP.
