Abstract (en)
For re-laminarizing a turbulent flow of a fluid flowing through a duct (4) in a main flow direction (6), a wall (5) of the duct (4) bounding the flow, additional fluid (9) is injected into the duct (4) in the main flow direction (6) as a sheet (11) of fluid covering the wall (5) in a circumferential direction around the main flow direction (6). Alternatively, a cylinder barrel structure is coaxially arranged within the pipe (2). The cylinder barrel structure comprises at least one cylinder barrel which is partly closed at its upstream end in the main flow direction, and the cylinder barrel structure - in the main flow direction - extends over at least twice a diameter (3) of the duct.
