Résumé

The flow and heat transfer characteristics of ice slurry were investigated experimentally. The characteristics in the transition region were examined in detail. The ice slurry was produced from ethanol solution. Ice packing factor (IPF), Reynolds number and tube diameter were varied as experimental parameters and the coefficients of pipe friction and heat transfer were measured. In the low IPF region, it was found that the coefficients of pipe friction and heat transfer were constant and the values were the same as that for turbulent flow of the ethanol solution. However, for the high IPF region, a laminarization phenomenon occurs and the flow and heat transfer characteristics can be estimated from the laminar flow of the ice slurry. Moreover, the laminarization point for the IPF can be predicted using the apparent Reynolds number.
