Abstract
Described is a new multilevel article comprising a multitude of ducts and, in each duct in the direction of flow, at least one area which generates turbulence, forms an open duct section, is connected to the duct wall, and forms a baffle for the incoming flow and a stall strip for the outgoing flow. The described article has a plurality of successive interconnected duct structures which form a step-like transition in relation to each other in the direct of flow.
Claims18
A multistage body having a plurality of flow channels, wherein each individual flow channel of the plurality of flow channels, in the flow direction in said individual flow channel, has at least one turbulence-generating surface, which forms a non-closed sub-channel and is attached to the channel wall, and which forms a baffle surface at flow entry and a separation edge for the flow at flow exit, and wherein the multistage body has multiple channel structures, which are connected in succession and form a stepped transition in relation to one another in the flow direction, wherein the baffle surface and the separation edge are arranged so that they occupy no more than 75% of the cross section of the individual flow channel.
