Abstract:
A static mixer comprising a group of deflector elements distributed within a conduit through which a fluid may flow in a direction generally parallel to an axis of the conduit, characterized in that the deflector elements are arranged in pairs of elements, the two deflector elements of each pair extending in a downstream direction from a common upstream leading edge and positioned generally opposite one another relative to the axis of the conduit to define between them on a downstream side an included angle of less than 180Â°, each of the two deflector elements defining a surface which is inclined to the conduit axis such that fluid is deflected by the inclined surface in a direction transverse to the axis of the conduit, and the two deflector elements of each pair having different configurations such that asymmetric vortices are generated by the two elements of the pair.
