On Atomization and Linearized Free-Surface Instability on Rotating Bodies

Abstract

A surface-wave instability theory applicable to spinning discs and cups is presented and a new explanation of atomization from these devices is proposed. The theory predicts an unstable disturbance wavelength that correlates with experimental results of Hinze and Milborn for ligament formation from a rotating cup. The linear analysis is restricted to flows where perturbation amplitude is much less than film thickness.
