An analysis on the statistical characteristics of static pressure pulsation in upward air-water flow through a smooth tube of 26.0 mm I. D. and 5.2 m long is made to have a correct understanding of the essentials of two-phase gas-liquid flow. The pulsating pressure is detected at five different locations along the tube and recorded simultaneously on an oscillograph paper. Using these data, the statistical properties such as the standard deviation, frequency function and spectral density of pulsating pressure are calculated. These are discussed with the particular emphasis on the relationship with the flow rates of both phases and the flow patterns.
