Thin Liquid Films and Wave Evolution on the Surface of a Rotating Disc
講演者:
William Paul Woods
摘要:
The steady-state flow of a liquid in the form of a thin film flowing
radially outward from a central source on the surface of a rapidly rotating
disc is examined, and both asymptotic and numerical solutions for the
flow-field and free surface location are presented. The conditions for
growth of small amplitude disturbances to the film are considered, and
various long-wave approximations are use to derive evolution equations for
large amplitude waves. These are compared with the equations governing
waves on a film falling down a vertical wall.
