Abstract
In this paper the static characteristics of the sharp edged orifices have been investigated.
Mathematical relationship between pressure loss and flow through the orifice has been developed and
solved for orifices mainly used in pilot operated pressure relief valves. A CFD simulation of the flowing
process has been done. A full CAD model of the volume for orifices with different geometric parameters was
created and meshed at finite number of elements. As a result of the CFD computations, few diagrams have
been presented and compared to the theoretical ones. The discharge coefficient and the pressure loss
coefficient have been obtained.
