Fluid pressure reduction device for high pressure-drop ratios

A fluid pressure reduction device comprises two or more stackable annular plates. Each disk having a perimeter and a hollow center aligned along a longitudinal axis when the annular plates are stacked one on top of the other. Each disk further comprising at least one inlet flow sector having an inle...

Zusammenfassung:	A fluid pressure reduction device comprises two or more stackable annular plates. Each disk having a perimeter and a hollow center aligned along a longitudinal axis when the annular plates are stacked one on top of the other. Each disk further comprising at least one inlet flow sector having an inlet flow stage for defining a first inlet area and a first outlet area, and at least one outlet flow sector having an outlet flow stage defining a second inlet area and a second outlet area, wherein the ratio of the second inlet area to the second outlet area is predetermined to define a backpressure at the outlet flow stage to provide a sub-sonic fluid flow at the perimeter.
