Abstract
A liquid film flow on a rotating disk and the scattering behavior are simulated using a three-dimensional incompressible SPH (Smoothed Particle Hydrodynamics) method. The liquid film simply flows out when the rotation is slow, whereas the liquid film breaks up to thin lines and eventually to numerous droplets when the rotation is fast. Those numerical results of the scattering liquid show good agreements with the experimental results. However, the effect of the size of the disk cannot be observed when the disk size is large due to not enough resolutions.
