Advanced simulation of naval pressure relief valve

The designing operation of pressure relief valve (PRV) was performed using NX Siemens. The purposes of this article are to evaluate different stages of real function of PRV when the pressure at the upstream is increasing step by step and the setting pressure of valve and the disc will be lifted. We simulate four different stages of valve evolution after the moment when the force exerted by the fluid on the disc approaches the spring force. The comparative CFD and FSI analysis are presented and interpretation of flow results (velocity, pressure and shear resultants) reflects the fluid structure interactions. (paper)
