Abstract

The invention relates to a device for controlling the swirl of a fluid (2, 7) flowing in a pipeline (1, 6), comprising a pipeline (1, 6) in which a fluid (2, 7) flows.

Description

(1) An example of the invention will be explained in more detail below on the basis of the drawing. FIG. 1 shows a basic illustration of a device according to the invention with a section of a pipeline 1 through which a fluid 2 (symbolized by an arrow here) flows.

(2) The pipeline 1 has a widened region 3, which is formed in a manner known per se (and not shown in more detail here) as a charge-air cooler.

(3) In the example provided, the fluid 2 exhibits a laminar flow in a first region 1A of the pipeline 1. By way of a swirl generator 4 (illustrated merely symbolically here), a predetermined swirl is able to be imparted to the fluid 2 such that the fluid 2 is able to be conducted through the charge-air cooler 3 with turbulent flow.

(4) In a second region 1B of the pipeline 1, which is arranged following the charge-air cooler 3 in the flow direction of the fluid 2, a flow straightener 5 (likewise illustrated merely symbolically) is arranged. By way of the flow straightener 5, the fluid 2 flowing from the charge-air cooler 3 in a turbulent manner is able to be transformed back into a laminar flow.

(5) FIG. 2 shows a section of a curved pipeline 6 having two bends 6A and 6B. A flowing fluid 7 (symbolized merely as arrow 7 here) is conducted through the pipeline 6.

(6) In this example, the fluid 7 flowing in at a first end 6C exhibits an unknown swirl.

(7) In the section shown, in the flow direction of the fluid 7, the pipeline 6 firstly has a flow straightener 8, by way of which the fluid 7 is able to be transformed into a laminar flow. Arranged downstream of the flow straightener 8 and upstream of the bend 6A of the pipeline 6 in the flow direction of the fluid 7 is a swirl generator 9, by way of which the flow of the fluid 7, which is laminar here, is able to be transformed into a turbulent flow with a predetermined swirl magnitude and swirl direction, which is matched to the bend 6A of the pipeline 6.

(8) In a swirl generator 10 which follows in the flow direction of the fluid 7, it is once again possible to intensify the swirl of the flowing fluid 7 upstream of the bend 6B of the pipeline 6, such that the fluid 7 is able to be conducted through the bend 6B with an optimal flow.
