Abstract
The operation of a pilot-operated pressure safety valve (PSV) are crucial to prevent the pressure system from overpressure. It is challenging to predict the dynamics behaviors of the valve due to its intricate structure with multiple components coupling. To address this issue, a co-simulation model with a one-dimension (1D) model for the PSV system and a three-dimension (3D) computational fluid dynamics (CFD) model for the main valve has been established in this paper. Dynamic analysis is conducted based on this model and response parameters like displacement and pressure are obtained for comparison with the experimental data. The different structural parameters are given for simulation to ascertain their effects on the dynamics of the PSV. Results demonstrate the efficacy of the co-simulation model in predicting the dynamic behaviors of the PSV and are helpful to improve the dynamic behaviors in design stage.
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.
