Abstract
A static mixer comprising a group of deflector elements distributed within a conduit through which a fluid flows in a direction generally parallel to an axis of the conduit. Each deflector element defines a surface which is inclined to the conduit axis such that fluid is deflected by the surface in a direction transverse to that axis. The deflector elements are positioned so as to generate an asymmetric vortex flow such that the intensities of adjacent vortices are different. The deflection elements may be in the form of, for example, asymmetric pairs of tabs, for example spaced apart pairs of tabs of different lengths. The angle of inclination of the tabs to the conduit axis may be adjustable.

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 180°, 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.
