Control of Droplet Characteristics in Liquid Atomization with Suspended Particles

The process of disintegration of liquid/solid suspension sheets and jets 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 a basic understanding and control of the suspension atomization process. Model suspensions based on water and water/glycerol mixtures with various suspended particles will be atomized by means of conventional and specifically designed atomizers.

The first year activities which are reported here include:

• Experimental investigations of atomization in rotary atomizers
• Stability Analysis and experimental investigation of twin fluid atomization

In order to provide a necessary data base for analysis and comparison, in the first year mainly the fluid behaviour has been studied.
