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.

大口径先导式压力安全阀的动态行为：联合仿真模型开发与测量

先导式压力安全阀（PSV）的运行对于防止压力系统超压至关重要。由于阀门结构复杂，多个部件相互耦合，因此预测阀门的动态行为具有挑战性。为解决这一问题，本文建立了 PSV 系统一维（1D）模型和主阀三维（3D）计算流体动力学（CFD）模型的联合仿真模型。根据该模型进行了动态分析，并获得了位移和压力等响应参数，以便与实验数据进行比较。本文给出了不同的结构参数进行模拟，以确定它们对 PSV 动态的影响。结果证明了联合模拟模型在预测 PSV 动态行为方面的功效，并有助于在设计阶段改进动态行为。

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.
