TABLE OF CONTENTS

A surface-wave instability theory applicable to spin-ning discs and cups is presented and a new explanation of atom-ization from these devices is proposed. The theory predicts an unstable disturbance wavelength that correlates with experi-mental 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. Preceding page blan
