Vorticity, Free Surface, and Surfactants

摘要: The central intent of this paper is to describe a number analyses and experi- ments that could eventually serve elucidate the physics fluid mechanics phe- nomena such as generation whirls, quasi-two-dimensionalization tur- bulence near free surface, reverse energy cascade at pure contam- inated interfaces. Discussed in some detail are vorticity flux; surface-tension effects; basic equations boundary conditions; role surfactants; topol- ogy interfacial interactions; characteristics connections, disconnections, reconnections; canonical flows (single paired vortices, jets, vortex rings); need for development prediction methods turbulent region bounded by free-surface, solid-fluid juncture layer nonlinear interactions shear flow wake turbulence with surface.
