The process of disintegration of liquid/solid suspension jets and sheets by atomization is analysed in a fundamental manner and visualized by suitable measurement methods, which allow qualitative and quantitative evaluation of the process. Supporting numerical analysis and theoretical derivations will contribute to basic understanding and control of the suspension atomization process. Model suspensions will be atomized by means of conventional and specifically designed atomizers.

The fith year activities that are reported here include:

- Further Experimental investigations of suspension atomization in twin-fluid atomizer

- Experimental investigations of atomization suspension sheet in flat pressure nozzle

Model suspensions based on water and glycerol/water-mixtures with different kind of suspended particles (Kaolin, Polymer, Glass) have been atomized by means of twin-fluid atomizer. Model suspensions based on water and Glycerol/water-mixture with suspended particles (glass and Kaolin) have been atomized by means of a flat pressure nozzle.
