Numerical modelling of a direct spring operated pressure relief valve

Abstract

This paper presents two methods for modeling the response of a direct spring operated pressure relief valve: one approach uses one-dimensional gas dynamical equations coupled with the equation of motion of a one degree-of-freedom oscillator, while the other employs deforming mesh CFD simulations to fully resolve the flow field. We found that if the force and flow rate characteristics of the valve are implemented into the reduced order model, it yields approximately the same results as the CFD computations.Mathematical Subject Classification: 76N15, 76-04
