RISExperimental Analysis of the Lift Force Discontinuity of a Spring-Loaded Pressure Safety Valve Working in Pneumatic Service
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Pressure safety valves (PSVs) are designed to provide ultimate protection for pressure systems. For design or optimization purpose, it is necessary to study the lift force exerted on the valve disk. Under special valve ...
A Method to Resolve Simulation of Discontinuous Flow Field: A Valve Example From Full Closing to Re-Closure
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In transient computational fluid dynamics (CFD) simulations, the continuity of the flow field is an essential prerequisite. However, continuous flows can be separated under certain conditions, such as the process from valve ...
Computational Fluid Dynamics Analysis of the Flow Force Exerted on the Disk of a Direct-Operated Pressure Safety Valve in Energy System
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The flow force acting on a valve disk plays an important role in the overall performance of pressure safety valves (PSVs). To quantify the disk force, computational fluid dynamics (CFD) methods have been widely implemented. ...
High-Fidelity Computational Fluid Dynamics Modeling and Analysis of a Pressure Vessel-Pipe-Safety Valve System in Gas Service
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A pressurized vessel-pipe-safety valve (PVPSV) system is a common configuration for many energy management systems, and a better understanding of their dynamics is helpful for system design and optimization. In this paper, ...
Dynamic Instability Analysis of a Spring-Loaded Pressure Safety Valve Connected to a Pipe by Using Computational Fluid Dynamics Methods
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: As the ultimate protection of a pressure system, pressure safety valves (PSV) can respond in an unstable manner in the form of flutter and chatter, which will affect service life, reliability, and performance. In order to ...
