Thermohydraulic effects of safety relief valves Original Research Article

An experimental study of the thermohydraulic performance of the safety relief valve (SRV) is presented. The study showed that the single and two-phase conditions upstream the SRV cause significant changes in the flow through the SRV. Five SRVs were tested covering a pressure range of (4.5–75) bar. A numerical solution of the transient one-dimensional, two-phase flow conservation equations by the method of characteristics was performed and predicted well the experimental data.
