安全阀超压泄放瞬态动力学数值模拟研究
Transient Dynamics Numerical Simulation Research for Safety Valve Overpressure Discharge Process
摘要
Abstract
Industrial safety valve is an important safety system component, which aims at preventing the system from over pressure and reducing further risk. Therefore, it is worth of work to study safety valve overpressure discharge dynamics mechanism. The paper is based on ANSYS CFX Dynamic Mesh techniques and CEL language to establish a safety valve dynamic equation concerning with the displacement of the valve disc. It has a preliminary access to solve the transient opening dynamic problem of safety valve. The relationship between transient parameter change attached to special path and opening process is acquired. It is shown by research that ANSYS CFX Dynamic Mesh techniques is feasible, it can be well applied to study the safety valve discharge mechanism关键词
