The results are helpful to improve the popping action of the valve in design stage, and demonstrate the availability and efficiency of using transient CFD simulation in the popping analysis of spring-loaded PSV.ġ4th International Conference on Pressure Vessel TechnologyĪ Fluid-Structure Interaction Analysis of the Spring-Loaded Pressure Safety Valve during Popping Off Response parameters such as the displacement of the disc, fluid force on the disc and the blowdown value are monitored to see their influence on the popping of the valve. Two types of time-dependent overpressure are given to simulate the popping of the PSV under different overpressure conditions. Fine structure grid has been generated over the whole flow domain to ensure that the valve disc can move freely and continuously without negative volume problem. To address this issue, a transient computational fluid dynamics ( CFD) model with moving grid technique has been presented in this work. It's difficult to observe the dynamics of the valve disc as well as the flow characteristics through the small chamber between the valve disc and valve seat over such a remarkable short period in the past. Popping off of a spring-loaded pressure safety valve (PSV) is crucial to prevent the pressure vessel or pipe from overpressure. One such problem is the popping off of pressure safety valve (PSV) widely used in pressure vessels and pipes.

Many industrial engineering problems require fluid-structure interaction (FSI) analysis and dynamics analysis to improve functionality or operational performance. Abstract of research paper on Materials engineering, author of scientific article - X.G.
