Cyclone laminating mixing

Cyclone mixers give a rotational flow field [109], The corresponding formation of vortex patterns is another way of laminating and focusing streams. It is hoped that by folding of the vortices, thinning of the lamellae can be achieved, with an increase of residence time in the mixer [131]. A full rotation should halve the lamellae width. Hence the optimization parameter may be to have as many rotations as possible. 

1 Mixer 49 [M 49] Cyclone Laminating Micro Mixer, Tangential Injection (I) 

This cyclone mixer comprises a spherical mixing chamber with 16equispaced nozzles which introduce the feeds tangentially at high (m s-1) fluid velocity [109] (see also [132]). 

Microstructuring was effected by dry reactive ion etching (DRIE) [109,132]. Two microstructured wafers were sandwiched between two powder-blasted wafers with through-holes and feed-rings.

Mixer type Cyclone laminating micro mixer, tangential injection Mixing chamber diameter 5 mm... 

This cyclone mixer comprises a cylindrical mixing chamber with many nozzles, arranged on the circular arc of the chamber (see Figure 1.113) [131]. At the the center of the floor of the chamber an outlet hole collects the multi-laminated streams.
