Abstract

Based the experiment of gas-liquid two-phase flow in horizontal pipes, a lot of datas of pressure, pressure difference were analyzed statistically, obtained and summarized the characteristics of probability density function (PSD) and power spectral density function (PDF) on three flow regime: stratified flow, slug flow, annular flow. And compared characteristics of PSD and PDF on pressure, pressure difference signal of differential flow regime. It found that PSD and PDF can be used for flow pattern identification, then provides a new reference method for flow pattern identification.
