WebWe present a stabilized POD–Galerkin reduced order method (ROM) for a Leray model. For the implementation of the model, we combine a two-step algorithm called Evolve-Filter (EF) with a computationally efficient finite volume method. In both steps of the EF algorithm, velocity and pressure fields are approximated using different POD basis and … WebThe pressure is just the weight of water in a column above a unit of area. You still need to know the relationship between pressure and velocity through the orifice, which is why I gave you a link to orifice flow. An orifice with sharp edges will have less velocity than one with a bell-shaped entrance, for example. $\endgroup$ –
