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. Support- ing numerical analysis and theoretical derivations will contribute to basic understand- ing and control of the suspension atomization process. Model suspensions will be atomized by means of conventional and specifically designed atomizers. The fourth year activities that are reported here include:

- Experimental investigations of suspension atomization in twin-fluid atomizer

- Experimental investigations of suspension atomization in rotary-atomizer

Model suspensions based on water with industrial relevant suspended particles (China Clay) have been atomized by means of twin-fluid atomizer. Model suspen- sions based on water and water/CMC-(carboxymetylcellulose) mixture with sus- pended glass particles have been atomized by means of a rotary atomizer.
