A review of research work of fluid dynamics of fine-crystalline ice slurry is presented. Different rheological models which are applied are presented. Numerous models for the friction factor, obtained by empirical and semi-empirical approximation, are discussed. An overview of existing pressure drop experiments is given and problematic issues of respective measurements and experimental results are outlined. Because ice slurry is a two-phase fluid that is considered to be homogeneous, only in some cases work on stratified suspension flows is cited. Finally a variety of experimental results and some theoretical calculations of ice slurry flow patterns are shown. (C) 2004 Elsevier Ltd and IIR. All rights reserved.
