Abstract

Film flow of liquids simulated by the third-grade model down a vertical longitudinally oscillating wall is investigated. The non-linear partial differential equation resulting from the momentum equation is solved by the method of Galerkin and flow enhancement is predicted for different material constants. It is also found that an increase in either the amplitude or frequency of the vibration always leads to an increase in the magnitude of the flow enhancement. © 1998 Elsevier Science Ltd.
