Abstract
The static mixer for a low viscosity fluid contains inbuilt devices effective for mixing, which are arranged in a pipe or in a container conducting the fluid. The inbuilt devices include structure elements in the form of flat, folded or curved sheet metal-like flow obstacles to form primary flow obstacles to achieve a flow of the first order. The structure elements are geometrically modified at surfaces and/or at edges so that local flows of the second order can be induced which are superimposed on the flow of the first order and so improve the mixing quality. Radial and axial inhomogeneities in the fluid are namely better compensated than by the flow of the first order.
