Detailed observations have been conducted on the impaction behavior between a falling liquid drop and a solid surface. Five kinds of solid surface have been tested to elucidate the effect of solid surface on the impaction behavior. The initial drop diameter was equal to 3.1 mm, and falling height of drop were varied from 100 mm to 1000 mm. Special attention has been directed to the dynamic process of drop spreading, and to the maximum diameter of the liquid drop spreading on the solid surface d_M. The ratio of maximum diameter d_M to the initial diameter d_L, i.e., the maximum diametral deformation ratio d_M/d_L, can be correlated by the Reynolds number with a viscosity of liquid Re_L. and the Ohnesorge number with liquid drop properties Oh.
