چکیده انگلیسی


• A multi-slot sampling device is proposed for gas-liquid two-phase flow metering.
• Theoretical correlation of gas and liquid extraction ratio is derived.
• Experiments were conducted at a gas-liquid two-phase flow loop.
• A spiral vane is used to adjust the inlet flow pattern into uniform annular flow.
• Effect of flow pattern on the gas and liquid extraction ratio was studied.

A novel approach to measure the individual mass flow rates of gas-liquid two-phase flow was proposed. Gas-liquid two-phase flow was divided into eighteen equal parts by a specially designed sampler and three parts were applied as sample fluid. The total gas and liquid flow rates are determined according to the flow rates of sampled fluid and the extraction ratio. The correlation of extraction ratio is deduced from the relation of resistance between the main loop and the division loop. Experiments were carried out in an air-water two-phase flow loop and the gas quality ranged from 0.008 to 0.66. The observed flow pattern included stratified smooth, stratified wavy, annular and slug flows. It was found that the gas and liquid extraction ratios are very close to the theoretical value (0.167) and independent of inlet flow pattern, gas and liquid velocities. The error of gas and liquid mass flow rates measurements was less than ±5.0%.
