• This study ultimately aims to make clear the nonlinear characteristics of the boiling two-phase flow and to construct a quantitative identification method of the flow pattern. At the first stage, a simple experiment of air-water two-phase flow in a vertical pipe was conducted under atmospheric pressure in the natural circulation. In the experiment, the differential pressure fluctuations of the various flow patterns were measured by a differential pressure sensor, and the signals were analyzed using some nonlinear measures such as reconstructed attractor, correlation dimension and Kolmogorov entropy. These flow patterns were observed by a high speed video camera. This paper shows that the randomlike differential pressure fluctuations of the flow patterns are chaotic and correlation dimension and Kolmogorov entropy may be the potential measures for the identification of the flow pattern in a vertical pipe.
