Zusammenfassung:[Display omitted] The deformation characteristics of the cavity due to droplet impact on a water surface are experimentally investigated. Dimensional analysis shows that the characteristic values of time, depth, and horizontal diameter can be taken as 10−3 times the ratio of surface tension to the product of viscosity coefficient and gravitational acceleration, the maximum depth, and the maximum horizontal diameter, respectively. The evolutions of the dimensionless cavity sizes for different values of Weber number (We) coincide for 220
