| 摘要 |
The present invention relates to a product for fluidic applications, with at least one surface segment having a plurality of ribs in contact with a fluid flowing in a flow direction and adjacent ribs delimit between them in each case a valley and a method for production and a use of such a product. The product according to the invention can be produced economically with further improved flow properties; in that at least two ribs with the valley they respectively delimit are combined in a group, that at least two groups are present, and separated from each group arranged adjacent to it, viewed transverse to the flow direction S of the fluid, by a valley, and that the height profile of the valley differs in each case from the height profile of the valleys delimited by those ribs of the groups which are adjacent to the valley separating the groups.
