Method and validity analysis of time-sharing and continuous measuring axial temperature and pressure in ejector
The conventional methods measuring flow parameters in ejector usually install some fixed instruments near the wall surface. Often only the fluid parameters and flow changes near the wall can be obtained. In order to obtain the axial fluid data of internal flow field in ejector, a time-sharing and continuous measuring axial temperature and pressure device is proposed in this paper. An ejector system experimental platform is setup based on the axial moving measurement device, and the experiment data is compared with the numerical simulation. The results show that the time-sharing and continuous measurement method is feasible, and the axial moving measurement device is a reliable, low-cost and convenient operation.
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.
