Multiinformative methods of experimental study of the structure and evolution of two-phase flows

Abstract

New experimental techniques based on fixation of gas-liquid interface image to control and describe 2D and 3D effects of two-phase flows are described. The developed signal processing algorithm enables to obtain extensive information about the behavior of a bubble and a liquid droplet in two-phase flows: its three-dimensional trajectory, the three component velocity fluctuations, the contour and size of the dispersed phase. Examples of using the developed technique for the study of two-phase bubble flows are provided.
