ABSTRACT

Solid-liquid mixing processes ”nd numerous applications in industry. The modeling of these mixing operations using ”rst principles is still limited, although some progress has been made in recent years. This study assesses the real capability of the network-of-zone approach in the case of a complex mixing problem involving a coaxial mixer. Coaxial mixers are very popular for the preparation of pastes and slurries in the chemical, food, and coating industries. The mixer considered is composed of two rotating shafts: a fastdriven shaft supporting an open impeller and a slow shaft driving a scraping anchor arm.
