  • New method for bubble/slug Velocity Measurement in small channels.
    The Review of scientific instruments, 2020
    Co-Authors: Xiao-yu Tang, Junchao Huang, Baoliang Wang, Zhiyao Huang
    Abstract:

    Based on the C4D technique and cross correlation Velocity Measurement technique, a new method for bubble/slug Velocity Measurement of the gas–liquid two-phase flow in small channels is proposed. A new C4D sensor, which is suitable for the parameter Measurement of the gas–liquid two-phase flow in small channels, is developed by introducing the principle of capacitive reactance elimination. With two new C4D sensors, a bubble/slug Velocity Measurement system is developed, and the bubble/slug Velocity is determined by the cross correlation Velocity Measurement technique. To verify the effectiveness of the proposed bubble/slug Velocity Measurement method, three prototypes of bubble/slug Velocity Measurement systems with different diameters (1.82 mm, 2.65 mm, and 2.96 mm, respectively) were established, and the bubble/slug Measurement experiments were carried out. The research results show that the capacitive reactance elimination is an effective way to overcome the unfavorable influence of the coupled capacitances on Measurement results. The experimental results indicate that the proposed method can successfully realize the bubble/slug Velocity Measurement in small channels, and the Velocity Measurement accuracy is satisfactory. For the three prototypes of the bubble/slug Velocity Measurement system, the maximum relative errors of the bubble/slug Velocity Measurement are all less than 5%.

  • A New Contactless Method for Velocity Measurement of Bubble and Slug in Millimeter-Scale Pipelines
    IEEE Access, 2017
    Co-Authors: Junchao Huang, Zhiyao Huang, Baoliang Wang
    Abstract:

    Combining C4D technique and cross-correlation Velocity Measurement technique, a new Measurement method, which is suitable for the bubble/slug Velocity Measurement in millimeter-scale pipelines, is proposed. Based on the series resonance principle and the simulated inductor technique, a new C4D sensor is developed. With two conductance signals obtained by two new C4D sensors (the upstream sensor and the downstream sensor), the bubble/slug Velocity Measurement is implemented by the cross-correlation Velocity Measurement technique. Experiments are carried out in three pipelines with different inner diameters of 4.50, 5.46, and 6.44 mm, respectively. The experimental results show that the proposed bubble/slug Velocity Measurement method is effective, the development of the new C4D sensor is successful, and the Velocity Measurement accuracy is satisfactory. The relative error of bubble Velocity Measurement is less than 5.41% and the relative error of slug flow Velocity Measurement is less than 4.90%.

  • A new method for the Velocity Measurement of gas-liquid two-phase flow
    2013 IEEE SENSORS, 2013
    Co-Authors: Ying Zhou, Zhiyao Huang, Baoliang Wang
    Abstract:

    The application potential of Capacitively Coupled Contactless Conductivity Detection (C4D) technique to the Velocity Measurement of gas-liquid two-phase flow in millimeter-scale pipe is investigated. Combining C4D technique and cross-correlation Velocity Measurement technique, a new Velocity Measurement method is proposed. The research work includes three parts. First, a three-electrode C4D sensor, which is suitable for the Velocity Measurement of gas-liquid two-phase flow in millimeter-scale pipe, is developed. Second, with the two independent conductivity signals of fluid obtained by the developed sensor, the Velocity Measurement of gas-liquid two-phase flow is implemented by the cross-correlation Velocity Measurement technique. Finally, Velocity Measurement experiments are carried out to verify the effectiveness of the proposed method. The research results indicate that the proposed Velocity Measurement method is effective and the developed sensor is successful. C4D technique may provide a useful approach for parameter Measurement of gas-liquid two-phase flow in millimeter-scale pipe.
