Jet Collision Turbulent or Swirling-flow Mixing

Jets can be collided frontal, i.e. at a 180° angle [52]. Here, the energy input is maximal. The fluid can be virtually atomized in this way and has to be surrounded by a mixing chamber to be re-collected. In a Y-type flow configuration, a softer contact can be achieved [39,136]. The two jets simply merge to a third one. Under unfavorable conditions, however, a separated, bi-laminated fluid system is achieved.

After jet merging, the material is brought out by an air stream, which redirects the merged stream by 90° into an outlet tubing [52,166], This is particularly done because a major application task of the mixer is to perform precipitation reactions. In the latter case, the mixed fluid is sprayed as small droplets or particles. If the droplets still contain solvent, nanoparticles can be produced by evaporation. 

No details on the geometry of the device and the fabrication were published.

The second type of mixer uses two impinging jets exiting from two borings to contact the reactants (for more detailed information, see Section 1.3.33, Jet Collision Turbulent or Swirling-flow Mixing).
