<p>The invention relates to a product for fluidic applications, having at least one surface section A provided for coming into contact with a fluid flowing in a flow direction S, wherein ribs 1, 1', 1" of a particular length L1, L2 and shape are formed in the section A coming into contact with the fluid, of which adjacent ribs 1, 1', 1" bound a depression 8, 8' between said ribs, to a method for producing same and to a use of such a product. The product according to the invention can be produced economically having further improved flow properties. The aim of the invention is achieved in that at least two ribs 1, 1', 1" and the depression 8, 8' bounded thereby are collected into a group G, G', at least two groups G, G1 are present, each group G, G' is separated by means of a depression 8, 8' from each adjacent group G, G1 as viewed transverse to the flow direction S of the fluid, and the height profile of the depression 12, 12' separating the groups G, G' from each other is different from the height profile of the depressions bounded by those ribs 1, 1', 1" of the groups G, G' simultaneously bounding the depression 12, 12' separating the groups G, G' from each other.</p> |
