Abstract

CDC valve is a multi-physics coupling system, where flow field simulation accuracy is crucial for dynamic characteristic analysis. This study develops a CFD-based thermo-fluid-structure coupling model, integrating interactions among flow, thermal, and stress fields, with experimental validation of its accuracy. Results show that the CDC valve reaches peak flow at 50 °C but exhibits a declining trend at higher temperatures. Under 30 °C and 6 MPa conditions, the maximum error between experimental and simulated flow rates is 7.46 %, demonstrating model reliability. This research reveals the dynamic behavior of the CDC valve under high-temperature and high-pressure conditions, providing theoretical support for optimized design and expanding multi-physics modeling of complex hydraulic components.

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.
