In process equipment, it is typical that uniform flow is desired upstream the component as this provides optimal performance. A well-known approach for creating uniform flows is using perforated plates. The perforated plate works by adding resistance governed by the flow velocity. As higher velocity will
result in a higher resistance, the flow will profile smoothen. This approach, and the resistance coefficients, are well documented in the literature. However, the literature does not present sufficient
information on how the velocity profile is after the perforated plate, especially if the velocity components are not normal to the plate. This presents an issue when performing CFD (Computational Fluid Dynamics) analysis using perforated plates modelled as porous media, as the flow downstream the
perforated plate will affect the reminding part of the simulation.
