Abstract

Cage-typed sleeve control valve (CSCV) is a critical component in direct coal liquefaction system. Gas-liquid-solid three-phase flow often occurs in the valve cage, which can cause cavitation and erosion wear. Consequently, the study of erosion wear and multiphase flow in the valve cage is necessary. A numerical model for multiphase flow is developed considering the momentum transfer between gas, liquid, and solid. To analyze the cavitation and erosion wear in the valve cage, the simplified stepped flow channel is designed. The Zwart-Gerber-Belamri cavitation model and Mansouri erosion wear model are used to analyze the erosion and cavitation inside the CSCV by numerical methods. Effects of particle concentration (ranging from 0.1 % to 0.5 %), particle velocity (ranging from 100 m/s to 150 m/s), and vapor phase on the erosion wear in the stepped flow channel are studied. The most severe erosion wear area in the stepped flow channel is the inner edge of the chamfer. The maximum erosion wear rate (R_max) on the chamfer increases with particle concentration and velocity. The vapor phase induced by cavitation primarily concentrates near the wall, which leads to the phenomenon that the particles move along the edge of the vapor phase and reduce the distribution of particles near the wall, thus mitigating the erosion wear on the wall of the inner orifice. This work can provide a reference for failure mechanism and prevention of CSCV and other similar valves.

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.
