Abstract
A static mixing device adapted to be inserted in a fluid stream having a main flow direction with respect to a closed conduit, comprises at least two tabs inclined in the flow direction at a preselected elevation angle between 10.degree. and 45.degree. to the surface of the conduit. The tabs are spaced apart in a direction transverse to the flow direction, the length and width of the tabs being selected so as to generate pairs of oppositely rotating predominantly streamwise vortices at the tips of each tab, and downstream hairpin vortices interconnecting adjacent streamwise vortices generated by a single tab.
