Switch valve simulation in dynamic simulation
Thread Content
For HYSYS dynamic simulation, it is necessary to simulate the instantaneous opening of a vent valve on a certain pipeline. To simplify the simulation, I used a control valve as a substitute. In the steady-state condition, I set a flow rate much lower than the normal value for this pipeline, and the valve opening was set at only 0.1%. The software then calculated a CV value based on the pressure drop and flow rate; however, I think this CV value is still too low. In the dynamic simulation, the pressure drop in this pipeline is mainly concentrated at this valve. I would like to ask how to simulate such a scenario
