Abstract

A secondary instability of the surface of a liquid film sheared by an intense gas flow was found for the first time by our team using the high-speed modified laser-induced fluorescence method. An image-analysis toolkit (in particular, the Canny method) was used for studying space-time evolution of various types of waves. As a result, quantitative characteristics of both the types of waves and the characteristics of the instability phenomena of back slopes of primary waves were obtained.
