Détermination de la distribution granulomeétrique de milieux dispersés liquide-liquide, solide-liquide et solide-solide: mise au point et développement de l'analyse d'image assistée par ordinateur

The dispersed-media granulometric distribution determination is often necessary. We mention the principal methods used nowadays with their own application fields and their limitations. Then we present the computer-assisted image analysis and its advantages.

The different aspects of this new method are developed, especially in the case of emulsions and granular systems. The statistical aspect needed for any results analysis is mentioned, and in particular the precision obtained as a function of the sample size.

Finally, we present a summary of the different advantages of computer-assisted image analysis, applied to the dispersed-media granulometric distribution determination.
