Abstract
Gas-liquid two-phase flow, a common multiphase flow, is widely present in petrochemical industry, aerospace technology, electric power generation, biopharmaceutical aspect, and other fields. Due to the complexity, randomness, and instability of its flow structure, accurate measurement of the gas-liquid two-phase flow parameter remains a challenging problem. For these above problems, in this study, an integrated sixteen-electrode dual-plane rotating electric field conductance sensor (DPREFCS) is designed for acquiring abundant flow information of gas-liquid two-phase flow in both time and space. Then a dual-parameter mixed boosting prediction model based on the Stacking ensemble learning algorithm is established for measuring the gas volume fraction and liquid volume flowrate of gas-liquid two-phase flow. The final prediction results illustrate this method can effectively measure the two parameters of gas-liquid two-phase flow, which provides a new approach for the multi-parameter measurement method of gas-liquid two-phase flow.
期刊介绍:
Flow Measurement and Instrumentation is dedicated to disseminating the latest research results on all aspects of flow measurement, in both closed conduits and open channels. The design of flow measurement systems involves a wide variety of multidisciplinary activities including modelling the flow sensor, the fluid flow and the sensor/fluid interactions through the use of computation techniques; the development of advanced transducer systems and their associated signal processing and the laboratory and field assessment of the overall system under ideal and disturbed conditions.
FMI is the essential forum for critical information exchange, and contributions are particularly encouraged in the following areas of interest:
Modelling: the application of mathematical and computational modelling to the interaction of fluid dynamics with flowmeters, including flowmeter behaviour, improved flowmeter design and installation problems. Application of CAD/CAE techniques to flowmeter modelling are eligible.
Design and development: the detailed design of the flowmeter head and/or signal processing aspects of novel flowmeters. Emphasis is given to papers identifying new sensor configurations, multisensor flow measurement systems, non-intrusive flow metering techniques and the application of microelectronic techniques in smart or intelligent systems.
Calibration techniques: including descriptions of new or existing calibration facilities and techniques, calibration data from different flowmeter types, and calibration intercomparison data from different laboratories.
Installation effect data: dealing with the effects of non-ideal flow conditions on flowmeters. Papers combining a theoretical understanding of flowmeter behaviour with experimental work are particularly welcome.
