The primary effect of a perforated plate component is an induced pressure loss in the direction of the fluid flow. The amount of pressure loss is related to the free area ratio (that is, the fraction of the plate that represents the perforations) and the thickness of the plate. In the current implementation, you represent a perforated plate using a simple block, which is an abstraction of the actual perforated plate geometry. You must select this block and mesh it before you can include it in the simulation. | |||||||||
