Abstract
We study rotary fragmentation dynamics and final droplet size distributions with a simple physical model. From animals drying their wet fur by rapidly shaking their body to automated rotary atomization in paint coating, centripetal acceleration is widely used to disintegrate liquid films into smaller fragments. However, little is known about the underlying physics and the liquid property effects on overall droplet size distributions. By performing a series of fragmentation tests with various viscous and viscoelastic liquids we are able to construct a simple and accurate physical model.
