RISAn Improved Positive Displacement Pump Model Accounting for Suction Cavitation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Positive displacement (PD) pumps are widely employed in industrial settings due to their inherent simplicity and reliability, serving a variety of applications from slurry transport to jet washing. Although their operational ...
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 ...
A Multidimensional and Multiscale Model for Pressure Analysis in a Reservoir-Pipe-Valve System
Publisher: American Society of Mechanical Engineers (ASME)
Abstract: Reservoir-pipe-valve (RPV) systems are widely used in many industrial processes. The pressure in an RPV system plays an important role in the safe operation of the system, especially during the sudden operations such as ...
