Significant studies 1–7 are being devoted to study solidification behavior of the droplet impact process. S.D. Aziz, S. Chandra 1 has studied the impact and solidification of molten tin droplets on a stainless steel surface. They observed the formation of fingers on the periphery of the droplet. S. Shakeri, S. Chandra 2 reported that thermal contact resistance is proportional surface roughness. At higher surface roughness, heat transfer from the droplet to the substrate is found to reduce, delaying the onset of solidification and reducing splashing. S. Kamnis, S. Gu3 has reported that air entrapment in splat, spreading, solidification behavior are dependent to surface roughness. S. Kamnis, S. Gu, T.J. Lu, C. Chen 4 developed numerical modelling of the dynamics of transient flow during the impact process, to study spreading, break-up, air entrapment and solidification of droplet.
