| Abstract: | A technique for void fraction and gas velocity measurements in two-phase gas-liquid bubbly flow is described. The double-point resistivity probe, appropriate signal-conditioning units and a personal computer have been integrated to form a data acquisition and analysis package enabling the determination of local flow properties. The system has been tested in an adiabatic air-water vertical up-flow situation and typical results are presented here. |
