Foam Generation and Air Entrainment Near a Free Surface
Abstract
The flow in a breaking wave is a type of agitation which is conducive to foam formation. The downstream wake of a surface vessel in the seaway also is characterized by a layer of foamy, agitated water near the surface, and a subsurface layer bubbles or a bubble cloud. The purpose of this report is to discuss the basic features of foam and bubble formation, and air entrainment as these features are known at the present time. We shall discuss possible means for relating these basic features to the processes of deep water wave breaking and of wake formation and development for surface ships moving in the seaway. Keywords: Surface foam, Bubbles, Air entrainment, Surfactants breaking waves, Ship wakes, Marine hydrodynamics.
