Momentum transfer of ice slurry flows in tubes, experimental investigations

In this paper we present results of the studies of ice slurry flow in horizontal tubes. The possibility of treating the theological parameters of ice slurry as being those of Bingham fluid was confirmed. The values of parameters (mass fraction, flow velocity) corresponding to the laminar, intermediate and turbulent flow were determined which permits to optimize the flow in the systems working with this cooling agent. Critical flow velocity and mass fraction of ice values were determined thereby; they correspond to a change in character of an ice slurry flow from a laminar to turbulent motion. Experimental results were compared to the analytical results, based on the Hedstrom and Tomita algorithms (the laminar and turbulent flow, respectively). The comparison showed a very good agreement between these data. (c) 2005 Elsevier Ltd and IIR. All rights reserved.
