PREFACE  

This volume of the Encyclopedia focuses on two-phase flows in which discrete solid parti-  

culates are dispersed in a continuum liquid phase. These flow systems are frequently encoun-  

tered in industrial operations, such as coal slurry pipeline transport, tertiary oil recovery  

practices, unit operations of industrial and municipal wastewater treatment, mining opera-  

tions, and liquid-phase polymerization reactors.
