Dynamics of Air-Blown Dimples

Abstract

A classical problem in fluid mechanics is that of a jet impinging on a solid surface. During the 1960's, partly driven by applications in the steel industry, the exploration of this field of study shifted towards the interaction between a gas jet and a deformable liquid surface, where often the shape of the deformation and its relation to the balance of forces were studied. This is also a very simplified representation of the interaction between the wind and the ocean. In this study, the dependence of the geometric properties, onset of oscillation and modes of oscillation were studied as a function of the air flow rate at the nozzle, defined as the jet Reynolds number, and the source height, given by the nondimensional nozzle height.
