Abstract

In order to achieve the void fraction measurement under different flow patterns, we develop the void fraction measurement method of gas–liquid two-phase flow based on multifiber optical probes in the horizontal collecting pipeline with small diameter in this paper. Specially, the flow characteristics and laws of the gas–liquid two-phase fluid are explored in horizontal small-diameter collecting pipeline; the structure of the multifiber optical probes is designed and optimized through Zemax simulation, and then the sensor with the optimal hexagonal seven-probe structure is developed and validated on the established experimental platform for void fraction measurement under different working conditions. Experimental results show that the developed void fraction measurement method based on the structure of multifiber optical probes has good applicability for void fraction measurement under different flow patterns in horizontal pipelines, and its measurement error does not exceed 0.07.

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.
