The numerical simulation of a droplet deformation and solidification on a cold substrate was performed with SMAC algorithm. The substrate temperature histories and the degree of deformation were measured by use of a droplet of n-eicosane and n-cetane. The numerical results showed good agreement with the measured ones. The solidification of a droplet on a substrate occurs immediately after the deformation. A simple model to estimate the deformation and the solidification time was also proposed. Both the normalized deformation and solidification time are proportional to the 0.2 power of the Reynolds number. The solidification time is two orders of magnitude higher than the deformation time.
