Abstract

A three-dimensional model of the plane mixing layer is constructed by applying digital image processing to laser fluorescence motion pictures of the layer, and displayed using computer graphic techniques. A system of streamwise counterrotating vortices is shown to exist on top of the classical spanwise eddies, and its influence in mixing is discussed briefly. Some quantitative information on their strength is also given.
