An analytic model of the flattening process based on assumptions considering both the particle deformation shape and flow field is presented. The deformation shape assumes that the thin disk begins to spread from the point of the particle impinging on the surface, and that the disk thickness is constant during the flattening process. The particle is divided into three regions, each with an assumed flow field that depends on time exponentially. The model describes the flattening ratios of molten particles as a function of time. The model was compared with experimental results of molten droplets allowing to fall freely onto flat surfaces. The flattening behavior of impinging molten tin and zinc droplets was photographed by high-speed camera and the spreading diameters of molten droplets were measured against time after impingement.
