ABSTRACT

A method of measuring an actual velocity of vapor flow in a two-phase flow on the basis of the system of technical vision is considered. To determine the velocity, the process of vapor-water mixture flow is recorded by a videocamera and then a certain sequence of frames is written in the computer memory where spatial shifts of statistically stable features of optical images are distinguished and analyzed.
