Abstract
This study deals with a sensing method of gas-liquid twophase flow in a horizontal pipe on the basis of statistical processing of differential pressure fluctuations. The experiment was carried out using nitrogen gas and water as working fluids. The flow pattern and void fraction and the velocity of gas phase were measured by PDF and cross-correlation of differential pressure fluctuations, respectively. The velocity of liquid phase, average void fraction, and flow quality were derived using a conservation law. The results suggest that the method is feasible for increasing the efficiency of an air conditioner.
