    Abstract

    : tion Classifica Subject s Mathematic 2010 76T10. Keywords: plug flow, differential pressure, probability density function, autocorrelation, power spectral density. Received February 15, 2012 Various measurement tools of statistic and chaos theory were applied to analyze two-phase flow plug. The experiments were carried out on an air-water flow in a horizontal pipe of i.d. 24 mm. These measurement tools included mean, standard deviation, skewness, kurtosis, probability density function, autocorrelation function, and power spectral density function. The statistical analysis represents physical phenomenon that mean, standard deviation, skewness, and kurtosis change linearly to the superficial velocity. The autocorrelation function and power spectral density function analysis demonstrate that the random like differential pressure fluctuations characteristics of plug flow are chaotic in nature.
