The fluid dynamics of ice slurry

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

Cold storage with ice slurries

The storage of 'cold' with ice slurries-a special type of thermally multi-functional fluids or phase change slurries (PCS)-is discussed. At first an example of a calculation of a thermal energy storage tank in an ice slurry system with a peak load demand is presented. Then a new concept of ice slurry storage without mixing is introduced. It leads to ice particle stratification and front propagation in the storage vessel. The stratification of ice particles in ice slurry is theoretically described by multi-component multi-phase fluid dynamics. The resulting stratification process is calculated and front propagation times are compared with experimental results; they compare fairly well. Copyright (C) 2007 John Wiley & Sons, Ltd
